Select with the CMD1 to CMD0 bits for the data transfer timing from the buffer register to the general
register. However, transfer with the following timing in spite of the value of the CMD1 to CMD0 bits for
the following cases:
Value in buffer register ≥ Value in TRDGRA0 register:
Transfer at the underflow in the TRD1 register.
And then, when setting the buffer register to 0001h or above and the smaller value than the one in the
TRDGRA0 register, and the TRD1 register underflows in the fist time after setting, the value is transferred
to the general register. After that, transfer the value with the timing selected by the CMD1 to CMD0 bits.

Operation When Value in Buffer Register ≥ Value in TRDGRA0 Register in
Complementary PWM Mode
The above applies to the following conditions:
• The CMD1 to CMD0 bits in the TRDFCR register are set to 11b.
• Both the OSL0 and OLS1 bits in the TRDFCR are set to 1. (active ‘H” for normal-phase and counter-phase)
(Data in the buffer register is transferred at the compare match in the TRD0 and TRDGRA0 registers in complementary
PWM mode.)
