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.
