M0519
6.7 Basic PWM Generator and Capture Timer (BPWM)
6.7.1 Overview
The NuMicro^® M0519 series has 1 set of BPWM group (BPWM0), supporting 1 set of BPWM
generators that can be configured as 2 independent BPWM outputs, BPWM0_CH0 and
BPWM0_CH1, or as 1 complementary BPWM pairs, (BPWM0_CH0, BPWM0_CH1) with
programmable dead-zone generator.
The BPWM generator has one 8-bit prescaler, one clock divider with 5 divided frequencies (1, 1/2,
1/4, 1/8, 1/16), two BPWM Timers including two clock selectors, two 16-bit BPWM down-counters
for BPWM period control, two 16-bit comparators for BPWM duty control and one dead-zone
generator. The BPWM generator provides two independent BPWM interrupt flags which are set
by hardware when the corresponding BPWM period down counter reaches zero.
Each BPWM interrupt source with its corresponding enable bit can cause CPU to request BPWM
interrupt. The BPWM generators can be configured as one-shot mode to produce only one
BPWM cycle signal or auto-reload mode to output BPWM waveform continuously. BPWM can be
used to trigger EADC when operation in center-aligned mode.
