(This specification is subject to change without prior notice)

Bit 3 (INT2 / INT3):

External INT2 and INT3 pins interrupt flag. Set by a falling edge

on the /INT2 and /INT3 pins, reset by software.

It can be used when Port 72 or Port 73 is set to input port.

Bit 2 (INT1): External INT1 pin interrupt flag. Set by a falling edge on /INT pin, reset by

software.

It can be used when Port 71 is set to input port.

Bit 1 (INT0): External INT0 pin interrupt flag. Set by a falling edge on /INT pin, reset by

software.

It can be used when Port 70 is set to input port.

Bit 0 (TCIF): TCC Timer Overflow Interrupt Flag. It will be set when TCC timer

overflows, reset by software.

INT0 ~ INT3 interrupts are edge triggering (falling edge or rising edge) which can be set

by CONT Bit 7 (INT_EDGE). Also, see corresponding interrupt mask in IOCF register.

User can read and clear.

RF can be cleared by instruction but cannot be set.

NOTE

The result of reading RF is the "Logic AND" of RF and IOCF.

5.1.17 R10 ~ R3F

R10 ~ R3F (Banks 0~3) are all general-purpose registers.
