Bit 2

T1BPOL: TP1B_0, TP1B_1, TB1B_2 Output polarity Control

0: Non-invert

1: Invert

This bit controls the polarity of the TP1B_0, TP1B_1, TP1B_2 output pin. When the bit is set

high the TM output pin will be inverted and not inverted when the bit is zero. It has no effect if the

TM is in the Timer/Counter Mode.

Bit 1~0

T1PWM1~T1PWM0: Select PWM Mode

00: Edge aligned

01: Centre aligned, compare match on count up

10: Centre aligned, compare match on count down

11: Centre aligned, compare match on count up or down
