IRQ7 to IRQ0 flags
Note: * When a product, in which a DTC is incorporated, is
used in the following settings, the corresponding flag bit is not
automatically cleared even when exception handling, which is a
clear condition, is executed and the bit is held at 1.
(1) When DTCEA3 is set to 1 (ADI is set to an interrupt source),
IRQ4F flag is not automatically cleared.
(2) When DTCEA2 is set to 1 (ICIA is set to an interrupt
source), IRQ5F flag is not automatically cleared.
(3) When DTCEA1 is set to 1 (ICIB is set to an interrupt
source), IRQ6F flag is not automatically cleared.
(4) When DTCEA0 is set to 1 (OCIA is set to an interrupt
source), IRQ7F flag is not automatically cleared.
When activation interrupt sources of DTC and IRQ interrupts
are used with the above combinations, clear the interrupt flag
by software in the interrupt handling routine of the
corresponding IRQ.

Bit 7 (Before)
0
[Clearing conditions]
• Cleared by reading IRQnF when set to 1, then writing 0 in IRQnF
• When interrupt exception handling is executed while low-level detection
• When IRQn interrupt exception handling is executed while falling, rising,
is set (IRQnSCB = IRQnSCA = 0) and IRQn input is high *
or both-edge detection is set (IRQnSCB = 1 or IRQnSCA = 1) *
