ODE - Open Drain Enable
GPW5:0 - GPW Data
These six bits contain the pulse width modulator data for the GPWM.
7.2
The RSPWM consists of a comparator and a 7-bit counter clocked by the positive edge of a clock
from the RCLK pin, and reset by the an active high signal from the PB7 pin. The RSPWM output
will be low after a counter reset, and high when the counter value matches the value in the
RSPWM register. Figure 7-3 shows example timings.
