When the value in the TRDGRA0 register is assumed as m, the TRD0 register counts order of m - 1, m, m
+ 1, m, m - 1 when changing from increment to decrement.
When changing from m to m + 1, the IMFA bit is set to 1. Also, the CMD1 to CMD0 bits in the TRDFCR
register are set to 11b (complementary PWM mode, buffer data transferred by the compare match in the
TRD0 and TRDGRA0 registers), the content in the buffer register (TRDGRD0, TRDGRC1, TRDGRD1) is
transferred to the general register (TRDGRB0, TRDGRA1, TRDGRB1).
For the order of m + 1, m, m - 1 operation, the IMFA bit remains unchanged and data are not transferred to
the register such as the TRDGRA0 register.
