Description
SS2 Trigger Select
This field selects the trigger source for Sample Sequencer 2.
The valid configurations for this field are:
Value Event
0x0
Processor (default)
The trigger is initiated by setting the SSn bit in the ADCPSSI
register.
0x1
Analog Comparator 0
This trigger is configured by the Analog Comparator Control
0 (ACCTL0) register (page 951).
0x2
Analog Comparator 1
This trigger is configured by the Analog Comparator Control
1 (ACCTL1) register (page 951).
