T1BOC: TP1B_0, TP1B_1, TP1B_2 Output control bit
This is the output control bit for the TM output pin. Its operation depends upon whether TM is
being used in the Compare Match Output Mode or in the PWM Mode/ Single Pulse Output Mode.
It has no effect if the TM is in the Timer/Counter Mode. In the Compare Match Output Mode it
determines the logic level of the TM output pin before a compare match occurs. In the PWM
Mode it determines if the PWM signal is active high or active low.
T1BPOL: TP1B_0, TP1B_1, TB1B_2 Output polarity Control
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.
