HARDWARE CONFIGURATION
(5) Output compare register (OUTCR)
This register is used to store the compare value of output compare.
When the values of this register and timer agree, the output is set.

(L)
In the PPG operation mode, the output is cleared by the external trigger or
(L)
software trigger input, and reset when the value of this register and the value
of the timer agree.
In the PWM operation mode, the output is reset by the external trigger or
software trigger input, and reset when the value of this register and the value
of the timer agree.
The pulse width can be specified by the value of this register.
(6) Output compare buffer register (OUTCBR)
This register is used to store the output compare value.
The value written to the output compare buffer register when the timer
stops is written directly to the output compare register.
(L)
Data transfer from the output compare buffer register to the output
compare register after the timer is started is done when the output
(L)
compare clear match occurs.

Note: Use the load instruction to write the value to the output compare
register buffer register during PWM or PPG operation. Some time
should be taken to allow writing of the load instruction to terminate
until the values of the output compare register and timer agree.
