7.3.2
CPUPCR sets whether or not the CPU has priority over the DTC, DMAC and EXDMAC. The
interrupt exception handling by the CPU can be given priority over that of the DTC, DMAC and
EXDMAC transfer. The priority level of the DTC is set by bits DTCP2 to DTCP0 in CPUPCR.
The priority level of the DMAC and EXDMAC is set by the DMAC and EXDMAC control
register for each channel.

CPU Priority Control Enable
Description
Controls the CPU priority control function. Setting this bit
to 1 enables the CPU priority control over the DTC,
DMAC and EXDMAC.
0: CPU always has the lowest priority
1: CPU priority control enabled
DTC Priority Level 2 to 0
These bits set the DTC priority level.
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)
