; CARD DECK IDENTIFICATION NUMBER: CR/C/0125
; MODULE IDENTIFICATION: NIC/558
; VERSION: 02
; DATED: 771207/FR
;
; COMMUNICATIONS PROCESSOR TEST DRIVE SYSTEM
;
; CPTDS - L3050 I/F TEST PROGRAM
;
; 5.3 SPECIAL DRIVER NARRATIVE.
; ------------------------------
; THIS MODULE OF THE CP TEST DRIVE SYSTEM (CPTDS) WILL BE USED TO
; LOOP ON SELECTED COM'DS IN ORDER TO VERIFY THE FUNCTION OF THE
; L3050 I/F. THE MODULE WILL REPLACE THE SUPERVISOR OF THE
; CP TEST DRIVE COMPUTER PROGRAM. ALL OTHER APPLICATION MODULES
; WILL NOT BE USED.
; THE IOX SIMULATOR (OR L3050 I/F MODULE TESTER) SHOULD HAVE THE
; DEVICE ADDRESS #06.
;
; THE PROGRAM WILL ASK THE OPERATOR FOR THE INPUT REQUIRED TO
; DETERMINE WHICH COM'D SEQUENCE TO LOOP UPON.
; UPON DETECTION OF A LINE FEED THE PROGRAM WILL START SERVICING
; THE CP WITH DEVICE ADDRESS #40 FOLLOWED BY CP WITH ADDR #80.
; THIS WILL BE REPEATED ENDLESSLY AS LONG AS THE PROGRAM IS ACTIVE.
; THE PROGRAM IS ABLE LOOPING ON ALL VALID COMMANDS.
;
; A.ADDRESSING.
; THE SPECIAL DRIVER SHALL BE ACTIVATED BY THE MONITOR UPON
; INITIALIZATION OF THE SYSTEM.
;
; B.ENTRY CONDITION.
; THE SPECIAL DRIVER SHALL BE ENTERED AS A CONSEQUENCE OF IT
; ACTIVATING ITSEFF DURING THE INITIALIZATION PHASE.
;
; C.EXIT CONDITIONS.
; THE MODULE WILL NEVER GIVE UP CPU TIME OR CONTROL TO ANY OTHER
; PROCESS IN THE SYSTEM IF IT HAS BEEN ACTIVATED.
;
; D.SPECIAL STORAGE. NONE.
;
; E.PROCCESSING.
; E1.INITIALIZATION.
; INITIATE: THE SPECIAL DRIVER IS CREATED, I.E. MADE KNOWN TO
; THE MONITOR (MON) AS IF IT WAS THE SUPERVISOR MODULE.
; LOCAL DATA AREAS ARE CLEARED.
; READOC: UPON WRITING '>' ON THE OC THE PROGRAM EXPECTS DATA
; TO BE ENTERED AS DESCRIBED BELOW. A CARRIAGE
; RETURN SHALL FLAG END OF CONTROL COM'D.
; E2.LOOP MODE.
; CPDRIVER:
; THE SPECIAL DRIVER IS CONTROLLED THROUGH THE CHARACTERS
; KEYED IN BY THE OPERATOR VIA THE OC KEYBOARD. THE BELOW
; DESCRIBE INPUT AND ACTION BY PROGRAM.
;
; 1) OI: OFR INVALID
; A LOOP WILL BE SET UP ON AN INVALID OFR COM'D.
; THE STATUS WILL BE PRINTED AS FOR 5 (SEE BELOW).
;
; 2) DM: DEV MASTER CLEAR.
; DI: DEV INTERRUPT PERMIT.
; A LOOP IS SET UP ON THE RECEIVED DEV COM'D.
; THE DISTANCE BETWEEN THE COM'DS ISSUED TO THE CP
; WILL BE ABOUT 150 USECS.
;
; 3) E : EOB
; LOOP ON EOB (H/W). EN EOB COMMAND WILL BE ISSUED
; TO THE L3050 I/F EACH 150 USEC.
;
; 4) DS: DEVICE STOP
; LOOP ON DEVICE STOP (H/W) - ELSE AS 2
;
; 5) O0: OFR 0
; O1: OFR 1
; O2: OFR 2
; O3: OFR 3
; A LOOP IS SET UP ON A SET OF OFR COM'DS ALL OF
; WHICH INVOLVE DATA TO BE TRANSFERRED TO AND FROM
; THE L3050 I/F OF THE CP SYSTEM. TWO OFRS WITH
; NON-IDENTICAL DATA TO BE TRANSFERRED SHALL BE USED
; WHILE THE REVERSE WILL BE IDENTICAL.
; THE OFRS USED ARE ALL BUILT-IN THE PROGRAM.
; EACH LOOP IS INITIATED BY A MASTER RESET COM'D
; TO BE FOLLOWED WITHIN 1 MSEC BY THE OFR COM'D.
; THE BUILT-IN OFR COM'D WILL BE SENT TO THE CP AND
; AFTER 1 MSEC THE DMA REQUESTS BE SERVED BY ENBL CP
; READ IF ANY INTR'PTS PENDING AND IF NOT SERVE THE
; AUTO OUTPUT TO THE MP I/F SIMULATOR. THE DMA WILL
; BE COMPLETED BY THE CP ACKNOWLEDGE INTERRUPT.
; HERE UPON A REVERSE BOOT (OFR COM'D TYPE 8) IS
; STARTED BY SENDING THE COM'D TO THE CP, WAIT 1 MSEC
; AND THEN SERVE THE DMA REQUESTS UNTIL THE RECEIPT
; OF THE CP ACKNOWLEDGE INTR'PT.
; A COMPARISON BETWEEN THE REVEIVED DATA AND THOSE
; ACTUALLY SENT ARE PERFORMED. THE STATUS OF THIS
; COMPARISON WILL BE SAVED FOR EACH RUN.
; AFTER LOOPCNT-1 (DEFAULT 1000) TEST RUNS THE
; RESULT WILL BE PRINTED AND THE INDICATORS RESET.
; THIS WILL BE REPEATED INDEFINITELY.
;
; IT MUST BE NOTED THAT THE PROGRAM DOES NOT USE THE
; INTERRUPT GENERATED BY THE INDICATOR AND REQUEST
; OF THE MP I/F SIMULATOR H/W BUT IN THE EVENT OF
; OF A MISSING REQUEST A LOOP OF 5 MES IS SET UP
; TO TAKE CARE OF THIS.
;
; IF THE NUMBER ENTERED AFTER THE 'OFR' IS NON-ZERO
; AN EOB WILL BE SENT TO THE CP SYSTEM WHEN 7 DATA
; (CP-)WORDS ARE LEFT TO BE TRANSFERRED. 1 WILL
; INTODUCE AN EOB IN THE MP TO CP TRANSFER (AUTO
; OUTPUT) WHILE 2 WILL INTRODUCE AN EOB IN THE CP TO
; MP TRANSFER (AUTO INPUT MODE).
; 3 WILL INTRODUCE EOBS IN BOTH DIRECTIONS.
; THE EOBS ARE SENT SUCH THAT THE LAST 7 CP-WORDS
; WILL NEVER BE TRANSMITTED.
;
; 6) MR: MASTER RESET.
; LOOP ON MASTER RESET (AS FOR 4).
;
; 7) MC: MASTER CLEAR.
; A SINGLE DEV MASTER CLEAR COM'D IS SENT TO BOTH
; CPS. UPON THIS THE PROGRAM WILL ASK FOR FURTHER
; DATA.
;
;
; 5.3.3. SPECIAL DRIVER INTERFACES.
; ---------------------------------
; A.INPUT DATA.
; WHEN THE PROCESS HAS BEEN ACTIVATED CONTROL IS NOT LEFT OVER
; TO ANY OTHER PROCESS.
;
;
; B.OUTPUT
; WHEN LOOPING ON NON-OFR COM'DS NO OUTPUT WILL BE DONE EXCEPT
; THE COM'DS SENT TO THE CP SYSTEM.
; THE OFR LOOP WILL AFTER EACH RUN HAVE ITS STATUS PRINTED ON THE
; LINE PRINTER:
;
; ...1.... BINARY PATTERN DESCRIBING A NUMBER OF CONDITIONS
; WHICH ARE CHECKED DURING EACH TEST LOOP. HIGH MEANS
; THAT THE CORRESPONDING CONDITION HAS BEEN PRESENT.
; THE BIT PATTERN IS TO BE INTERPRETED AS FOLLOWS:
; 0 WORD RECEIVED NOT MATCHING THAT SENT
; 4 REQUEST RECEIVED IN INTERVAL 105 USEC - 5 MEC.
; 5 NO REQUEST RECEIVED AFTER 5 MSECS.
; 6 OVERRUN, I.E. TOO MANY REQ'S RECEIVED.
;
; DDDDD TOTAL NUMBER OF REQUESTS RECOGNIZED BY THE PROCESS
; DURING THE TOTAL LOOP. THIS WILL HAVE TO EQUAL
; 2*(NO OF LOOPS)*(2+(WORDCOUNT/2)+1+1)
; WORDCOUNT BEING THE NO OF DATA WORDS INVOLVED
; IN THE BOOT LOADING USED - OFR 2/8.
;
; 2*HHHH HEX DUMP OF THE INTEGRATED CP ACKNOWLEDGE INTR'PT
; RECEIVED AFTER EACH DMA TRANSFER. THE FIRST WILL
; FOR THE AUTO OUTPUT (MP->CP) WHILE THE SECOND IS
; FOR THE AUTO INPUT (CP->MP) DATA TRANSFER.
;
; 8*DDDD COUNTERS ASSOCIATED WITH THE BIT PATTERN DESCRIBED
; ABOVE.. EACH TIME THE SPECIFIC CONDITION HAS BEEN
; PRESENT THE ASSOCIATED COUNTER WILL BE INCREASED
; BY ONE.
;
; HHHH HEX DUMP OF INTEGRATED STATUS BEFORE ENABLE
; HHHH HEX DUMP OF STATUS FOR MP -> CP AFTER ENABLE
; HHHH HEX DUMP OF STAUTS FOR CP -> MP AFTER ENABLE
;
;
; THE PROGRAM CAN BE PATCHED IN THE PROCEDURE 'XFERERR' TO PRINT
; FAULTY DATA RECEIVED BY THE CP SYSTEM. NOTE THAT IN THIS PRINT
; -OUT DATA MATCHING IN FRONT OF WORD-IN-ERROR WILL ALL HAVE BEEN
; ZEROED. ALSO ONE LINE WILL BE PRINTED FOR EACH ERROR DETECTED.
;
; LARGE PARTS OF THE PROGRAM HAS BEEN DIRECTLY COPIED FROM THE
; CPTDS MODULE 'MP I/F DRIVER'.
