NOTES:
1. This Reduced DMA Cycle Time is selected by setting CSR2 bit 15, CYCLE = 1.
2. Output delay times are the maximum delay from the specifed edge to a valid output.
3. The Bus Master cycle time will increase from a minimum, in 1 SYSCLK increments
Times T0 and T5 from the standard DMA Cycle are removed for this reduced timing.
until the slave device returns READY.
