(4) Interrupt mask flag (
(5) Interrupt request flag (
502
An interrupt mask flag specifies enabling/disabling of vectored interrupt processing and macro service processing for
the interrupt request corresponding to that flag.
The interrupt mask contents are not changed by the start of interrupt processing, etc., and are the same as the interrupt
mask register contents (see 20.3.2 Interrupt Mask Registers (MK0/MK1L)).
Macro service processing requests are also subject to mask control, and macro service requests can also be masked
with this flag.
This flag can be manipulated in software.
RESET input sets all bits to “1”.
An interrupt request flag is set (1) by generation of the interrupt request that corresponds to that flag. When the interrupt
is acknowledged, the flag is automatically cleared (0) by hardware.
This flag can be manipulated in software.
RESET input sets all bits to “0”.
