16-bit counter is cleared from FFFFH to 0000H, starts counting, and outputs a one-shot pulse from the TOQ0b pin.
After the one-shot pulse is output, the 16-bit counter is cleared to 0000H, stops counting, and waits for a trigger.
When the trigger is generated again, the 16-bit counter starts counting from 0000H. If a trigger is generated again
while the one-shot pulse is being output, it is ignored.
count value matches the value of the CCR0 buffer register. 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.

When the TQ0CE bit is set to 1, 16-bit timer/event counter Q waits for a trigger. When the trigger is generated, the
The output delay period and active level width of the one-shot pulse can be calculated as follows.
The compare match interrupt request signal INTTQ0CC0 is generated when the 16-bit counter counts after its
The valid edge of the external trigger input (TRGQ0) and setting the software trigger (TQ0CTL1.TQ0EST bit) to 1
Remark
Output delay period = (Set value of TQ0CCRb register) × Count clock cycle
Active level width = (Set value of TQ0CCR0 register − Set value of TQ0CCRb register + 1) × Count clock cycle
(a) TMQ0 control register 0 (TQ0CTL0)
(b) TMQ0 control register 1 (TQ0CTL1)
Note The setting is invalid when the TQ0CTL1.TQ0EEE bit = 1.
