HT66F20-1/HT66F30-1/HT68F20-1/HT68F30-1
Flash MCU with EEPROM
T1BOC: TP1B_0, TP1B_1 Output control bit
Bit 3
Compare Match Output Mode
0: Initial low
1: Initial high
PWM Mode/Single Pulse Output Mode
0: Active low
1: Active high
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 Output polarity Control
0: Non-invert
1: Invert
This bit controls the polarity of the TP1B_0, TP1B_1 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
