Am79C974
Slave I/O Write
The Slave I/O Write command is used by the host CPU
to write to the Am79C974’s CSRs, BCRs and EEPROM
locations and SCSI and CCB registers. It is a single cy-
cle, non-burst 8-bit, 16–bit, or 32-bit transfer which is
initiated by the host CPU. The typical number of wait
states added to a slave I/O write access on the part of
the Am79C974 controller is 6 to 7 clock cycles. The
Am79C974 controller will not produce Slave I/O write
commands while being a bus master.
