(This specification is subject to change without prior notice)

Bit 2 (TCCE): Define the function of P56/TCC pin

TCCE = "0": for bidirectional general I/O pin

TCCE = "1": for external input pin of TCC, the control bit of P56 (Bit 6 of IOC50)

must be set to

“1”

Bit 1 (EINT1): Define the function of P55/INT1 pin

EINT1 = "0": for bidirectional general I/O pin

EINT1 = "1": for external interrupt pin of INT1, the control bit of P55 (Bit 5 of

IOC50) must be set to

“1”

Bit 0 (EINT0): Define the function of P54/INT0 pin

EINT1 = "0": for bidirectional general I/O pin

EINT1 = "1": for external interrupt pin of INT0, the control bit of P54 (Bit 4 of

IOC50) must be set to

“1”

These bits are set to

“1” when interrupt occurs.

Bit 7 (ICIF): Port 6, Port 8, input status changed interrupt flag. Set when Port 6, Port 8

input changes.

Bit 6 (LPWTF): Interrupt Flag of the internal Low-Pulse Width Timer underflow.

Bit 5 (HPWTF): Interrupt Flag of the internal High-Pulse Width Timer underflow.

Bit 4 (CNT2F): Interrupt Flag of the internal Counter 2 underflow.

Bit 3 (CNT1F): Interrupt Flag of the internal Counter 1 underflow.

Bit 2 (INT1F): External INT1 pin Interrupt Flag

Bit 1 (INT0F): External INT0 pin Interrupt Flag

Bit 0 (TCIF): TCC timer overflow Interrupt Flag. Set when TCC timer overflows.
