Note: * Reserved: These bits are always read as 0. The write value should always be 0.
As shown in table 10.2, on-chip peripheral module or IRQ 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 of H'0 means priority level 0 (masking
is requested); H'F means priority level 15 (the highest level).
