2.9.2 DMAC Transfer Cycles
Any combination of even or odd transfer read and write addresses is possible. Table 2.9.2 shows the
number of DMAC transfer cycles.
The number of DMAC transfer cycles can be calculated as follows:
No. of transfer cycles per transfer unit = No. of read cycles ! j + No. of write cycles ! k
