TMP88FW45FG
18. 8-Bit High-speed PWM (HPWM0 and HPWM1)
The TMP88FW45FG contains two-channels of high-speed PWM. The high-speed PWM works in such a way that
when data are written to the data registers for the respective channels, waveforms differing from each other can be
output.
The high-speed PWM is shared with ports, P02 (HPWM0) and P03 (HPWM1). When using these pins for high-
speed PWM, set the port output latches for P02 and P03 to 1.
