8.1.5
Communication between the controlling system and
processor unit is defined by a sequence protocol.
Communication between the controlling system and
processor unit is implemented using control bit in the
output and input buffer.
Basic sequence
1. The controller sends a command designator to the
processor unit in the output buffer with the AV bit set.
The AV bit tells the processor unit that a job is
beginning and the transmitted data is valid.
2. The processor unit accepts the job and confirms the
job by setting the AA bit in the input buffer.
3. If additional data needs to be exchanged for the job,
readiness for additional data exchange is indicated by
inverting the TI and TO toggle bits.
4. The processor unit has correctly executed the job and
sets the AE bit in the input buffer.
5. The controller has accepted all data. The AV bit in the
.
hex
output buffer is reset.
6. The processor unit resets all control bits set in the input
buffer during the job (AA bit, AE bit). The processor unit
is ready for the next job.
