Description
SS3 Trigger Select
This field selects the trigger source for Sample Sequencer 3.
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 1251).
0x2
Analog Comparator 1
This trigger is configured by the Analog Comparator Control
1 (ACCTL1) register (page 1251).
0x3
Analog Comparator 2
This trigger is configured by the Analog Comparator Control
2 (ACCTL2) register (page 1251).
0x4
External (GPIO Pins)
This trigger is connected to the GPIO interrupt for the
corresponding GPIO (see “ADC Trigger Source” on page 668).
0x5
Timer
In addition, the trigger must be enabled with the TnOTE bit
in the GPTMCTL register (page 757).
0x6
PWM generator 0
The PWM generator 0 trigger can be configured with the
PWM0 Interrupt and Trigger Enable (PWM0INTEN) register
(page 1300).
0x7
PWM generator 1
The PWM generator 1 trigger can be configured with the
PWM1INTEN register (page 1300).
0x8
PWM generator 2
The PWM generator 2 trigger can be configured with the
PWM2INTEN register (page 1300).
0x9
PWM generator 3
The PWM generator 3 trigger can be configured with the
PWM3INTEN register (page 1300).
