mode
A summary of operations in these modes follows.
I/O Mode: One byte or word is transferred per request. A designated number of these transfers are
executed. A CPU interrupt can be requested at completion of the designated number of transfers.
One 24-bit address and one 8-bit address are specified. The transfer direction is determined
automatically from the activation source.
Idle Mode: One byte or word is transferred per request. A designated number of these transfers
are executed. A CPU interrupt can be requested at completion of the designated number of
transfers. One 24-bit address and one 8-bit address are specified. The addresses are held fixed. The
transfer direction is determined automatically from the activation source.
Repeat Mode: One byte or word is transferred per request. A designated number of these transfers
are executed. When the designated number of transfers are completed, the initial address and
counter value are restored and operation continues. No CPU interrupt is requested. One 24-bit
address and one 8-bit address are specified. The transfer direction is determined automatically
from the activation source.
