Read operation using READ command in BIS M-4008

Example: Read 30 bytes at read/write head, start address 10:


Once enough data has been read to fill the input buffer of R/W head1, the data will be carried over to the input buffer.


The AE bit is not set until the compact processor unit has finished the “Read” operation. The reply “Job end” (AE bit) is reliably set no later than before the last data has been sent.


This time point depends on the requested volume of data and the time response of the controller. In the example, the use of italics for “Set AE bit” calls your attention to this fact.
