2.9.8 Analog Inputs
The Zynq Ultrascale+ MPSoC devices contain a system monitor in the PL and an additional system monitor
block in the PS. These are used to sample analog inputs and to collect information on the internal voltages
and temperatures.
The system monitor block in the PL provides a 10-bit ADC, which supports up to 17 external analog lines (1
dedicated differential input, 16 auxiliary differential inputs). The auxiliary analog lines of the MPSoC device
are available on the module connector; these I/Os have the abbreviation “AD” followed by the ADC channel
7
UART RX is an MPSoC input; UART TX is an MPSoC output.

Used for PCIe PERST# connection implementation. Refer to Section 2.9.2 for details.
