42.1.3 LPIT input triggers
LPIT is designed to capture small pulses at its input trigger irrespective of its clock
frequency as mentioned in MWCT101xS_Trigger_Muxing.xlsx attached to the Reference
manual. But for reliable back to back operation these triggers should be spaced apart by
at least 10 LPIT bus clock cycles.
42.1.4 LPIT/ADC Trigger
The LPIT could be used as an alternate ADC hardware trigger source, the implementation
is through TRGMUX. Each LPIT channel supports one pre-trigger and one trigger. The
LPIT channels are implemented based on independent counters. When used as ADC
trigger source, the channel outputs generate the ADC hardware triggers and pre-triggers.
The following diagram shows an example of using LPIT triggering ADC0.
The LPIT triggers can also have multiple sources. Refer to ADC Trigger Sources .
