29.4.8.1 Trigger Outputs

The PTG module can generate up to 32 unique trigger output signals. There are two types of trigger output functions:
  • Individual
  • Broadcast

The PTG module can generate an individual output trigger on any one of the trigger outputs using the PTGTRIG command.

The individual trigger outputs may be assigned to various functions, such as ADC conversion triggers or PPS input/output signals. PPS signals can be routed to external pins or used as inputs to certain other peripherals; refer to the Peripheral Pin Select (PPS) Overview chapter for more information.

The broadcast trigger output feature is specified by the PTGBTE register. Each bit in the register corresponds to an associated individual trigger output. If a bit is set in the PTGBTE register, and a broadcast trigger step command (‘PTGCTRL 0b1111’) is executed, the corresponding individual trigger output is asserted. The broadcast trigger output enables the user to simultaneously generate a large number of trigger outputs with a single step command.
