When bit PWM0 is set to 1 to select PWM mode, pin TIOCA
output goes to 1 at compare match with GRA0, and to 0 at compare match with GRB0.
10.2.4 Timer Function Control Register (TFCR)
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.
