11.5.6
There are the following update methods for transfer destination and source addresses: Fixed,
increment/decrement by 1, 2 or 4, and offset addition. With the offset addition method, the offset
specified by the offset register (EDOFR) is added each time the EXDMAC performs a data-
access-size transfer. This function allows the mid-addresses being skipped during data transfer.
Figure 11.17 shows the address update methods.
For the fixed method (a), the same address is always indicated without the transfer destination or
source address being updated.
For the method of increment/decrement by 1, 2 or 4 (b), the value corresponding to the data access
size is incremented or decremented to or from the transfer destination or source address each time
the data is transferred. A byte, word, or longword can be specified for the data access size. The
value used for increment or decrement of an address is 1 for a byte-size , 2 for a word-size , and 4
for a longword-size transfer. This function allows continuous address transfer of EXDMAC.
