Select with bits CMD1 to CMD0 the timing of data transfer from the buffer register to the general register.
However, transfer takes place with the following timing in spite of the value of bits CMD1 to CMD0 in the
following cases:
Value in buffer register ≥ value in TRDGRA0 register:
Transfer take place at underflow of the TRD1 register.
After this, when the buffer register is set to 0001h or above and a smaller value than the value of the
TRDGRA0 register, and the TRD1 register underflows 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 11b (data in the buffer register is transferred at compare match
• Both the OSL0 and OLS1 bits in the TRDFCR register are set to 1 (active ‘H” for normal-phase and counter-phase).
