PRODUCTION DATA
There are eight external SOC triggers that go to each of the two ADC modules (from the Control Subsystem). In addition to the eight external SOC triggers, there are also two internal SOC triggers derived from EOC interrupts inside each ADC module (ADCINT1 and ADCINT2). Registers INTSOCSEL1 and 2 are used to configure each of the 16 ADC channels for internal or external SOC sources. If internal SOC is chosen for a given channel, the INTSOCSEL1 and 2 registers also select whether the internal source is ADCINT1 or ADCINT2. If external SOC is chosen for a given ADC channel, the TRIGSEL field of the corresponding SOCxCTL register selects which of the eight external triggers is used for SOC in that channel. One analog-to-digital conversion can be performed at a time by the 12-bit ADC. The analog-to-digital conversion priority is managed according to the state of the PRICTL register.
