Interrupt Priority Set Enable
Controls the function which automatically assigns the
interrupt priority level of the CPU. Setting this bit to 1
automatically sets bits CPUP2 to CPUP0 by the CPU
interrupt mask bit (I bit in CCR or bits I2 to I0 in EXR).
0: Bits CPUP2 to CPUP0 are not updated automatically
1: The interrupt mask bit value is reflected in bits
CPUP2 to CPUP0

CPU Priority Level 2 to 0
These bits set the CPU priority level. When the
CPUPCE is set to 1, the CPU priority control function
over the DMAC becomes valid and the priority of CPU
processing is assigned in accordance with the settings
of bits CPUP2 to CPUP0.
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:
*
When the IPSETE bit is set to 1, the CPU priority is automatically updated, so these bits
cannot be modified.
