The count source fOCO40M can be used with supply voltage VCC = 2.7 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 takes place at compare match between registers TRD0 and TRDGRA0.
After this, when the buffer register is set to 0001h or above and a smaller value than the value of the
TRDGRA0 register, and a compare match occurs between registers TRD0 and TRDGRA0 for the first time
after setting, the value is transferred to the general register. After that, the value is transferred with the timing
selected by bits CMD1 to CMD0.

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