6.3
6.3.1
Interrupt priority registers A to E (IPRA to IPRE) are 16-bit readable/writable registers in which
priority levels from 0 to 15 are set for on-chip peripheral module, IRQ, and PINT interrupts. These
registers are initialized to H'0000 by a power-on reset or manual reset, but are not initialized in
standby mode.
Table 6.7 lists the relationship between the interrupt sources and the IPRA—IPRE bits.
Table 6.7
Note: * Always read as 0. Only 0 should be written.
As shown in table 6.7, on-chip peripheral module, IRQ, or PINT interrupts are assigned to four 4-
bit groups in each register. These 4-bit groups (bits 15 to 12, bits 11 to 8, bits 7 to 4, and bits 3 to
0) are set with values from H'0 (0000) to H'F (1111). Setting H'0 means priority level 0 (masking
is requested); H'F is priority level 15 (the highest level). A reset initializes IPRA–IPRE to H'0000.
