Description
Memory Wait Insertion —Specifies the number of wait
states introduced into CPU or DMAC memory access
cycles. MWI1 and MWI0 are set to 1 during RESET. See
section on Wait State Generator for details.
Wait Insertion — Specifies the number of Wait States
introduced into CPU or DMAC I/O access cycles. IWI1
and IWI0 are set to 1 during RESET. See section on Wait
State Generator for details.
DMA Request Sense — Specifies the DMA request
sense for channel 0 (DREQ0) and channel 1 (
respectively. When reset to 0, the input is level-sense.
When set to 1, the input is edge-sense.
DMA Channel 1 I/O and Memory Mode — Specifies
the source/destination and address modifier for channel 1
memory to/from I/O transfer modes. Reference Table 15.
