6.3.1
IPRA to IPRH are 16-bit readable/writable registers in which priority levels from 0 to 15 are set
for on-chip peripheral module, and IRQ and PINT interrupts.
Bit
15 to 0
Table 6.2
Register
Note: * Always read as 0. The write value should always be 0.
As shown in table 6.2, on-chip peripheral module, or 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 means priority level 15 (the highest level).
