10.2.4
TFCR is an 8-bit readable/writable register that selects complementary PWM mode, reset-
synchronized PWM mode, and buffering for channels 3 and 4.
TFCR is initialized to H'C0 by a reset and in standby mode.
Bits 7 and 6—Reserved: Read-only bits, always read as 1.
Bits 5 and 4—Combination Mode 1 and 0 (CMD1, CMD0): These bits select whether channels
3 and 4 operate in normal mode, complementary PWM mode, or reset-synchronized PWM mode.
