The count source fOCO40M can be used with supply voltage VCC = 3.0 to 5.5 V. For supply voltage other than
that, do not set bits TCK2 to TCK0 in registers TRDCR0 and TRDCR to 110b (select fOCO40M as the count
source).
When the value in the buffer register is set to 0000h:
Transfer by the compare match in the TRD0 and TRDGRA0 registers.
And then, when setting the buffer register to 0001h or above and the smaller value than the one in the
TRDGRA0 register, and the compare match in the TRD0 and TRDGRA0 registers 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.

The above applies to the following conditions:
• The CMD1 to CMD0 bits in the TRDFCR register are set to 10b.
• Both the OLS0 and OLS1 bits in the TRDFCR register are set to “1” (active “H” for normal-phase and counter-phase).
(Data in the buffer register is transferred at the underflow in the TRD1 register in PWM mode.)
