AFE MUX
The AFE MUX is a 16-channel MUX that resides in the AFE. The AFE MUX is used for the
internal analog bus that is connected to the output of the differential amplifier, single-ended
amplifiers and other channels found in the CAFE.
The MUX select for the AFE MUX may also be controlled directly through the SOC registers or
through the EMUX from the MCU’s DTSE.
When the ADC is configured for manual mode, the EMUX enable function in the AFE should be
disabled. To select the AFE MUX channel using the SOC registers, set
SOC.SHCFG1.EMUXEN
to 0b (disabled). The MUX channel may be selected from
SOC.SHCFG2.MUXA
.
When the ADC is configured for DTSE mode, the EMUX enable function in the AFE should be
enabled. To select the AFE MUX channel using the EMUX set
SOC.SHCFG1.EMUXEN
to 1b
(enabled). The AFE MUX channel may be selected from the EMUX data sent from the DTSE.
The channels available on the AFE MUX are shown in the table below.
