Bit 5 (PWM2IE) PWM2IF interrupt enable bit.
0: disable PWM2 interrupt
1: enable PWM2 interrupt
Bit 6 (CMPIE) CMPIF interrupt enable bit.
0: disable CMPIF interrupt
1: enable CMPIF interrupt
Bit 7: Unimplemented, read as ‘0’.
Individual interrupt is enabled by setting its associated control bit in the IOCF0 to "1".
Global interrupt is enabled by the ENI instruction and is disabled by the DISI instruction. Refer to Fig.
11.
IOCF0 register is both readable and writable.

Bit 7 (PWM2E): PWM2 enable bit
0 = PWM2 is off (default value), and its related pin carries out the P52 function.
1 = PWM2 is on, and its related pin will be set to output automatically.
Bit 6 (PWM1E): PWM1 enable bit
0 = PWM1 is off (default value), and its related pin carries out the P51 function;
1 = PWM1 is on, and its related pin will be set to output automatically.
Bit 5 (T2EN): TMR2 enable bit
0 = TMR2 is off (default value).
1 = TMR2 is on.
Bit 4 (T1EN): TMR1 enable bit
0 = TMR1 is off (default value).
1 = TMR1 is on.
