PWM waveform from the TOQ0b pin.
written value is reflected when the count value of the 16-bit counter matches the value of the CCR0 buffer register and
the 16-bit counter is cleared to 0000H.
after its count value matches the value of the CCR0 buffer register, and the 16-bit counter is cleared to 0000H. The
compare match interrupt request signal INTTQ0CCb is generated when the count value of the 16-bit counter matches
the value of the CCRb buffer register.
TQ0CTL0
TQ0CTL1
When the TQ0CE bit is set to 1, the 16-bit counter is cleared from FFFFH to 0000H, starts counting, and outputs
The active level width, cycle, and duty factor of the PWM waveform can be calculated as follows.
The PWM waveform can be changed by rewriting the TQ0CCRa register while the counter is operating. The newly
The compare match interrupt request signal INTTQ0CC0 is generated when the 16-bit counter counts next time
Remark
Active level width = (Set value of TQ0CCRb register ) × Count clock cycle
Cycle = (Set value of TQ0CCR0 register + 1) × Count clock cycle
Duty factor = (Set value of TQ0CCRb register)/(Set value of TQ0CCR0 register + 1)
(a) TMQ0 control register 0 (TQ0CTL0)
(b) TMQ0 control register 1 (TQ0CTL1)
Note The setting is invalid when the TQ0CTL1.TQ0EEE bit = 1.
