PWRMON MUX
The PWRMON MUX is an 8-channel MUX that resides in the AFE. The PWRMON MUX allows
the user to sample internal power regulators for diagnostic purposes without dedicating an
external ADC channel.
The MUX select for the PWRMON MUX is always controlled through the SPI bus by writing
SOC.PWRCTL.PWRMON
.
The PWRMON MUX output is on the analog bus channel AB11, which is directly connected to
the AFE MUX.
The channels available on the PWRMON MUX are shown in the table below.
