Device Functions
1. Reading 30 bytes at R/W head 1, start address 10
Once enough data has been read during the execution of the read job to fill the input buffer for
R/W Head 1, the data will be transmitted to the input buffer. The AE bit is not set until the
processor unit has finished the "Read" operation.
The "Job End" (AE bit) response is reliably set no later than before the last data has been sent.
This timing 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.
