The Interrupt Request Mask Register (IMASK) is used to finally determine whether or not to accept an interrupt
request after comparing its priority with the priority levels (Interrupt Control Register ILEVEL bits) that have been
set for each interrupt request source.
When the Interrupt Vector Register (IVECT) described above is read, the interrupt priority level of the accepted
interrupt request source is set in this IMASK register as a new mask value.
When any value is written to the IMASK register, operations (1) to (2) below are automatically performed in
hardware.
(1) The interrupt request (EI) to the CPU core is deasserted.
(2) The ICU’s internal sequencer is activated to start internal processing (interrupt priority resolution).
Notes: Do not write to the Interrupt Request Mask Register (IMASK) in the EIT handler unless interrupts
are disabled (PSW register IE bit = "0").
To reenable interrupts (by setting the IE bit to "1") after writing to the Interrupt Request Mask
Register (IMASK), perform a dummy access to the internal memory, etc. before reenabling inter-
rupts.
