Sample Buffering Setup Procedure: Figure 10.48 shows a sample buffering setup procedure.
Select general register functions
Complementary PWM mode
The buffer register value is transferred to the general register when TCNT3 and TCNT4
change counting direction. This occurs at the following two times:
Reset-synchronized PWM mode
The buffer register value is transferred to the general register at compare match A3.
When TCNT3 compare matches GRA3
When TCNT4 underflows
Buffered operation
Start counters

Set TIOR to select the output compare or input
capture function of the general registers.
Set bits BFA3, BFA4, BFB3, and BFB4 in TFCR
to select buffering of the required general registers.
Set the STR bits to 1 in TSTR to start the timer
counters.
