Legend: - = unimplemented, read as ‘0’.

T12MOD : TMR1 operation mode select bit.

= 1, The TMR1 and TMR2 in PWM mode operation.

= 0, The TMR1 and TMR2 in Timer mode operation.

PWMS : Initial State of PWM1P output duty.

= 1, Set the initial state to L, change to H when TMR2 duty underflow.

= 0, Set the initial state to H, change to L when TMR2 duty underflow.

POPS :

PWM Output Pin Select bit.

= 1, The PWM1P output from IOB1.

= 0, The PWM1P output from IOA0.

PIR13:PIR10 : Interrupt Event Rate of PWM1.

“1:N” means interrupt occurred after “N” PWM1 pulses.
