Analog-to-Digital Converter (ADC)
Register 8: ADC Trigger Source Select (ADCTSSEL), offset 0x01C
If a PWM Generator n is selected as a trigger source through the EMn bit field in the ADC Event
Multiplexer Select (ADCEMUX) register, the ADCTSSEL register is programmed to identify in
which PWM module instance the generator creating the trigger is located. The register resets to
0x0000.0000, which selects PWM module 0 for all generators. Note that field PS3 selects the PWM
module that maps to Generator 3; PS2 selects the PWM module that maps to Generator 2, and so
on.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Generator 3 PWM Module Trigger Select
This field selects in which PWM module the generator 3 trigger is located.
Value Description
0x0
Use Generator 3 (and its trigger) in PWM module 0
0x1
Use Generator 3 (and its trigger) in PWM module 1
