Register
Registers TRDGRC0, TRDGRC1, TRDGRD0, and TRDGRD1 are not used in PWM3 mode. To use them as
buffer registers, set bits BFC0, BFC1, BFD0, and BFD1 to 0 (general register) and write a value to the
TRDGRC0, TRDGRC1, TRDGRD0, or TRDGRD1 register. After this, bits BFC0, BFC1, BFD0, and BFD1
may be set to 1 (buffer register).
