EXDMA Priority Levels 2 to 0

Selects the EXDMAC priority level when using the CPU

priority control function over DTC and EXDMAC. When

the EXDMAC priority level is lower than the CPU

priority level, EXDMAC masks the acceptance of

transfer source and waits until the CPU priority level

becomes low. The priority level can be set

independently for each channel. This bit is enabled

when the CPUPCE bit in CPUPCR is 1.

000: Priority level 0 (lowest)

001: Priority level 1

010: Priority level 2

011: Priority level 3

100: Priority level 4

101: Priority level 5

110: Priority level 6

111: Priority level 7 (highest)

Note:

Only 0 can be written to these bits after 1 is read to clear the flag.
