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)
