30.2 Architectural Overview

The PTG module is a user-programmable sequencer for generating complex peripheral trigger sequences. The PTG module provides the ability to schedule complex peripheral operations, which would be difficult or impossible to achieve via a software solution.

The user writes 8-bit commands, called step commands, to the PTG Queue registers (PTGQUE0-PTGQUE7). Each 8-bit step command is made up of a command code and an option field. Table 30-5 shows the format and encoding of a step command. Based on the commands, the PTG can interact with other peripherals, such as the PWM, ADC, SCCP/MCCP and Peripheral Pin Select. See the device-specific data sheet for availability of peripherals.
