7.4 Functional Description
7.4.1 PWM Capabilities
This section describes some capabilities of the PWM module.
7.4.1.1 Center Aligned PWMs
Each submodule has its own timer that is capable of generating PWM signals on two
output pins. The edges of each of these signals are controlled independently as shown in

These bits represent the sampling period (in IPBus clock cycles) of the fault pin input filter. Each input is
sampled multiple times at the rate specified by this field. If FFILT[FILT_PER] is 0x00 (default), then the
input filter is bypassed. The value of FFILT[FILT_PER] affects the input latency.
