Count value in TRD0
The TRD1 register counts 1, 0, FFFFh, 0, 1, in that order, when changing from decrement to increment
operation.
The UDF bit is set to 1 when changing between 1, 0, and FFFFh operation. Also, when bits CMD1 to CMD0
in the TRDFCR register are set to 10b (complementary PWM mode, buffer data transferred at underflow in
the TRD1 register), the content in the buffer registers (TRDGRD0, TRDGRC1, and TRDGRD1) is
transferred to the general registers (TRDGRB0, TRDGRA1, and TRDGRB1). During FFFFh, 0, 1 operation,
data are not transferred to registers such as the TRDGRB0 register. Also, at this time, the OVF bit remains
unchanged.
