120 / 244 page  HT68F20/HT68F30/HT68F40/HT68F50/HT68F60 HT68FU30/HT68FU40/HT68FU50/HT68FU60 Rev. 1.50 120 March 15, 2011 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. 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.
