This register provides the comparison encodings that generate an interrupt and/or PWM trigger.
See “Interrupt/ADC-Trigger Selector” on page 1023 for more information on using the ADC digital
comparators to trigger a PWM generator.

Reset Description
0x0000.0
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.
0
Comparison Trigger Enable
Value Description
1 Enables the trigger function state machine. The ADC conversion
data is used to determine if a trigger should be generated
according to the programming of the CTC and CTM fields.
0 Disables the trigger function state machine. ADC conversion
data is ignored by the trigger function.
