(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.
Table 8-2. Function of Capture/Compare Register in Each Mode and How to Write Compare Register
Interval timer
External event counter
External trigger pulse output
One-shot pulse output
PWM output
Free-running timer
Pulse width measurement
Triangular wave PWM mode
The TABnCCR0 register can be rewritten even when the TABnCTL0.TABnCE bit = 1.
The set value of the TABnCCR0 register is transferred to the CCR0 buffer register. When the value of the 16-
bit counter matches the value of the CCR0 buffer register, a compare match interrupt request signal
(INTTABnCC0) is generated. If TOABn0 pin output is enabled at this time, the output of the TOABn0 pin is
inverted.
When the TABnCCR0 register is used as a cycle register in the interval timer mode, external event count mode,
external trigger pulse output mode, one-shot pulse output mode, PWM output mode, or triangular wave PWM
mode, the value of the 16-bit counter is cleared (0000H) if its count value matches the value of the CCR0 buffer
register.
When the TABnCCR0 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 TABnCCR0 register if the valid edge of the capture trigger input pin (TIABn0
pin) is detected. In the pulse width measurement mode, the count value of the 16-bit counter is stored in the
TABnCCR0 register and the 16-bit counter is cleared (0000H) if the valid edge of the capture trigger input pin
(TIABn0 pin) is detected.
Even if the capture operation and reading the TABnCCR0 register conflict, the correct value of the TABnCCR0
register can be read.
