A block diagram of the internal multiplexing feature is shown in
multiplexing of four external signals to an SIU output. A 2-bit SEL field from an SIU select register defines
the input to the multiplexor.

eQADC External Trigger Input Multiplexing
The six eQADC external trigger inputs can connect to one of the following pins:
•
External pin
•
eTPU channel
•
eMIOS channel
The input source for each eQADC external trigger is configured in the eQADC trigger input select register
(SIU_ETISR). As shown in the figure, you can select one of the following signals to source to the
ETRIG[0] input to the eQADC:
•
ETRIG[0]_GPIO[111] pin
•
ETPUA[30] output channel
•
EMIOS[10] output channel
•
GPIO[206] pin
All ETRIG inputs are multiplexed in the same manner. If an eTPU or eMIOS channel is selected as an
ETRIG input to the eQADC, you can activate the alternate function of that eTPU or eMIOS signal on the
external pin.
