DMAC
(1) Transfer cycle
The transfer cycle consists of the bus cycle in which data is read from memory or from the SFR area
(source read) and the bus cycle in which the data is written to memory or to the SFR area (destination
write). The number of read and write bus cycles depends on the source and destination addresses
and the software waits are inserted.
(a) Effect of source and destination addresses
When 16-bit data is transferred on a 16-bit data bus, and the source and destination both start at odd address-
es, there is one more source read cycle and destination write cycle than when the source and destination both
start at even addresses.
(2) DMAC transfer cycles
Any combination of even or odd transfer read and write addresses is possible. Table 14 show the num-
ber of DMAC transfer cycles. Table 15 shows the corresponding coefficient values. Figure 57 shows
an example of the transfer cycle for a source read.
The number of DMAC transfer cycles can be calculated as follows:
Number of transfer cycles per transfer unit = Number of read cycles x j + Number of write cycles x k
