"1" means interrupt request, "0" means non-interrupt
Bit 0(TCIF) : TCC timer overflow interrupt flag
Set when TCC timer overflows.
Bit 1(CNT1) : counter1 timer overflow interrupt flag
Set when counter1 timer overflows.
Bit 2(CNT2) : counter2 timer overflow interrupt flag
Set when counter2 timer overflows.
Bit 3(INT0) : external INT0 pin interrupt flag
If PORT70 has a falling edge/rising edge (controlled by CONT register) trigger signal, CPU will set this bit.
Bit 4(INT1) : external INT1 pin interrupt flag
If PORT71 has a falling edge trigger signal, CPU will set this bit.
Bit 5(INT2) : external INT2 pin interrupt flag
If PORT72 has a falling edge trigger signal, CPU will set this bit.
Bit 6(DETO) : CTCSS tone detection interrupt flag
If CTCSS detection output signal(R7 PAGE1 bit 6) has an edge signal (falling edge, falling and rising
edge), CPU will set this bit.
Bit 7(INT3) : external INT3 pin interrupt flag
If PORT73 has a falling edge trigger signal, CPU will set this bit.
<Note> IOCF is the interrupt mask register. User can read and clear.
