7.3
7.3.1
Interrupt priority registers A to G (IPRA to IPRG) are 16-bit read/write registers that set priority
levels from 0 to 15 for on-chip supporting module, IRQ, and PINT interrupts. These registers are
initialized to H'0000 at power-on reset, and manual reset, but are not initialized in standby mode.
Table 7.7 lists the relationship between the interrupt sources and the IPRA to IPRG bits.

Note: * Always read as 0. Only 0 should be written in.
As listed in table 7.7, four sets of on-chip supporting modules or IRQ or PINT interrupts are
assigned to each register. 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 to IPRG to H'0000.
