(a) Function as compare register
(b) Function as capture register
The following table shows the functions of the capture/compare register in each mode, and how to write data to
the compare register.
The TQ0CCR3 register can be rewritten even when the TQ0CTL0.TQ0CE bit = 1.
The set value of the TQ0CCR3 register is transferred to the CCR3 buffer register. When the value of the
16-bit counter matches the value of the CCR3 buffer register, a compare match interrupt request signal
(INTTQ0CC3) is generated. If TOQ03 pin output is enabled at this time, the output of the TOQ03 pin is
inverted.
When the TQ0CCR3 register is used as a capture register in the free-running timer mode, the count value
of the 16-bit counter is stored in the TQ0CCR3 register if the valid edge of the capture trigger input pin
(TIQ03 pin) is detected. In the pulse-width measurement mode, the count value of the 16-bit counter is
stored in the TQ0CCR3 register and the 16-bit counter is cleared (0000H) if the valid edge of the capture
trigger input pin (TIQ03 pin) is detected.
Even if the capture operation and reading the TQ0CCR3 register conflict, the correct value of the
TQ0CCR3 register can be read.
