STATE Describes current LDU in output. Since the
possible type of TMS output buffers differ
from what the OUTPUTTER requires the CONTROLLER
must itself keep track. (The reason being the
HEAD output)
HEAD, HEAD ̲BUFFER ̲ENTRY.
The HEAD word will always be the first two
bytes TMS outputs for control output.
