NuMicro M0518 Series Datasheet
6.8 Basic PWM Generator and Capture Timer (BPWM)
6.8.1 Overview
The M0518 provides two BPWM generators － BPWM0 and BPWM1 Each BPWM supports 6
channels of BPWM output or input capture. There is a 12-bit prescaler to support flexible clock to
the 16-bit BPWM counter with 16-bit comparator. The BPWM counter supports up, down and up-
down counter types, all 6 channels share one counter. BPWM uses the comparator compared
with counter to generate events. These events are used to generate BPWM pulse, interrupt and
trigger signal for ADC to start conversion. For BPWM output control unit, it supports polarity
output, independent pin mask and tri-state output enable.
The BPWM generator also supports input capture function to latch BPWM counter value to
corresponding register when input channel has a rising transition, falling transition or both
transition is happened.
