21.3.5 Interrupt source determination flag register 0 (INTFLG0)
This register determines which of interrupt sources causes an interrupt, an external interrupt source (INTP4, 5, 8, 13) or
other interrupt source that are allocated to the same vector table address as the comparator detection 0 interrupt source.
The flag in this register cannot be set by software.
The flags are cleared by software.
To clear the flag, write 1 to the bits other than the bit desired to be cleared.
Use an 8-bit data transfer instruction as a write instruction.
