Complementary PWM Mode: When the count direction of TCNT3 and TCNT4 change, the BR
value is transferred to the GR. The following timing is employed for this transfer:
Reset-Synchronized PWM Mode: The BR value is transferred to GR upon a GRA3 compare
match.
Procedure for Selecting the Buffer Mode (figure 10.47):
1. Set the TIOR to select the output compare or input capture function of the GR.
2. Set bits BFA3, BFB3 and BFB4 in the TFCR to select the buffer mode for the GR.
3. Set the STR bit in the TSTR to 1 to start the TCNT counting.
Whenever TCNT3 and GRA3 compare-match
Whenever TCNT4 underflows
