Simultaneous Sampling Mode (Dual-Channel) (SMODE = 1)
In simultaneous mode, the ADC can continuously convert input signals on any one pair of channels (A0/B0
to A7/B7). The ADC can start conversions on event triggers from the Event Managers (EVA/EVB), software
trigger, or from an external ADCSOC signal. If the SMODE bit is 1, the ADC will do conversions on two selected
channels on every Sample/Hold pulse. The conversion time and latency of the Result register update are
explained below. The ADC interrupt flags are set a few SYSCLKOUT cycles after the Result register update.
The selected channels will be sampled simultaneously at the falling edge of the Sample/Hold pulse. The
Sample/Hold pulse width can be programmed to be 1 ADC clock wide (minimum) or 16 ADC clocks wide
(maximum).
NOTE:
In Simultaneous mode, the ADCIN channel pair select has to be A0/B0, A1/B1, ...,
A7/B7, and
not
in other combinations (such as A1/B3, etc.).
