Complementary PWM Mode: When the counter switches from counting up to counting down or

vice versa, the value of the buffer register is transferred to the general register. Here, the value of

the buffer register is transferred to the general register in the following timing:

1. When TCNT_0 and GRA_0 are compared and their contents match

2. When TCNT_1 underflows

Reset Synchronous PWM Mode: The value of the buffer register is transferred from compare

match A0 to the general register.

Example of Buffer Operation Setting Procedure: Figure 12.37 shows an example of the buffer

operation setting procedure.

[1] Designate GR as an input capture register

or output compare register by means of

TIOR.

[2] Designate GR for buffer operation with bits

BFD1, BFC1, BFD0, or BFC0 in TMDR.

[3] Set the STR bit in TSTR to 1 to start the

count operation of TCNT.
