Section 5 Interrupt Controller
Note:
5.3.3
IPR sets priory (levels 7 to 0) for interrupts other than NMI and sleep interrupt.
Setting a value in the range from B'000 to B'111 in the 3-bit groups of bits 14 to 12, 10 to 8, 6 to 4,
and 2 to 0 assigns a priority level to the corresponding interrupt. For the correspondence between
the interrupt sources and the IPR settings, see table 5.2.

Interrupt Priority Registers A to C, E to I, K, L, Q, and R
(IPRA to IPRC, IPRE to IPRI, IPRK, IPRL, IPRQ, and IPRR)
When the IPSETE bit is set to 1, the CPU priority is automatically updated, so these bits
cannot be modified.

Description
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 DTC and 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)
