transfer function is selected). The DMAC II index stores parameters for transfer mode, transfer counter,
source address (or immediate data), operation address as an address to be calculated, destination ad-
dress, chained transfer address, and end-of-transfer interrupt address.
This DMAC II index must be located on the RAM area.
Figure 13.2 shows a configuration of the DMAC II index. Table 13.2 lists a configuration of the DMAC II
index in transfer mode.
The followings are details of the DMAC II index. Set these parameters in the specified order listed in
Table 13.2, according to DMAC II transfer mode.
The DMAC II index is a data table which comprises 8 to 18 bytes (maximum 32 bytes when the multiple

The DMAC II index must be located on the RAM. Necessary data is set front-aligned. For example, if not using a calculation
transfer function, set destination address to BASE+6. (See Table 13.2)
Starting address of the DMAC II index must be set in the interrupt vector for the peripheral function interrupt causing a DMAC II request.
