2nd Bit Header
If the 1st and 2nd bit headers match, the data is valid.
Communication between the controlling system and processor unit is defined by a trace.
Communication between the host control system and the processor unit is implemented using a
control bit in the output and input buffers.
Basic sequence
1. The controller sends a command identifier to the processor unit in the output buffer with the
AV bit set.
The AV bit tells the processor unit that a job is starting and that 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 into the input buffer.
5. The controller has accepted all of the data. The AV bit in the output buffer is reset.
6. The processor unit resets all of the control bits set in the input buffer during the job
(AA bit, AE bit). The processor unit is ready for the next job.
Note
All specifications are typical values. Deviations are possible depending on the
application and combination of R/W head and data carrier.
The specifications apply to static operation; no CRC_16 data checking.
All specified read/write times are based on the communication between the data
carrier and the read/write head. The times for the data communication between the
processor unit and the host control system are not included.
