In reset synchronous PWM mode, TCNT_0 and TCNT_1 perform increment and independent
operations, respectively. However, GRA_1 and GRB_1 are separated from TCNT_1. When a
compare match occurs between TCNT_0 and GRA_0, a counter is cleared and an increment
operation is restarted from H'0000.
The PWM pin outputs 0 or 1 whenever a compare match between GRB_0, GRA_1, GRB_1 and
TCNT_0 or counter clearing occur.
For details on operations when reset synchronous PWM mode and buffer operation are
simultaneously set, refer to section 13.4.8, Buffer Operation.
