10.3.6
Interrupt Mask Registers 0 to 10 (IMR0 to IMR10)
IMR0 to IMR10 are 8-bit readable/writable registers that mask the
IRQ
and on-chip peripheral
module interrupts. When an interrupt source is masked, interrupt requests may be mistakenly
detected, depending on the operation state of the IRQ pins and on-chip peripheral modules. To
prevent this, set IMR0 to IMR9 while no interrupts are set to be generated, and then read the new
settings from these registers.
Table 10.3 shows the relationship between IMR and each interrupt source.

Interrupt Mask
Table 10.3 lists the correspondence between the
interrupt sources and interrupt mask registers.
IMn
1: Interrupt source of the corresponding bit is masked.
0: When reading, Interrupt source of the corresponding
bit is not masked. When writing, No processing.
