Table 114 Initiating AUXADC Measurements
In Polling mode, setting AUXADC_POLL = 1 initiates one set of measurements, after which the
AUXADC waits for a new trigger.
In Continuous mode, a set of measurements will be initiated at the frequency set by
AUXADC_CRATE.
When using MASK to initiate measurements (AUXADC_MASKMODE=11), a rising edge (if
GPn_CFG = 1) or a falling edge (if GPn_CFG = 0) initiates one set of AUXADC measurements. The
MASK signal must be asserted for long enough for the AUXADC to perform all the selected
measurements.
The AUXADC_SELn bits should not be changed until all previous measurement results stored in the
AUXn readback registers have been read.

AUXADC MASK input control
00 = MASK is ignored
01 = When MASK is asserted, all
AUXADC measurements are
inhibited.
10 = Reserved
11 = MASK input initiates AUXADC
measurements. AUXADC_POLL
and AUXADC_CTC have no effect.
MASK polarity is controlled by
GPn_CFG.
