8.4 Operation

8.4.1 Overview

Table 8-5 summarizes the DMAC modes.

Table 8-5 DMAC Modes

Transfer Mode

External request

A summary of operations in these modes follows.

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.

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.
