mux - Multiplex Control

Warning

The Multiplexer sub-system of the PLT only tolerates voltages up to 5.5V.

Control which signals are routed through the multiplex channels.

Usage:

- command: mux <channel> <signal>

- command: mux connect|disconnect all|<signal>

Argument	Description
channel	Multiplex channel (0..3)
connect	Connect a signal probe to the multiplexer
disconnect	Disconnect a signal probe from the multiplexer
signal	Probe or signal
all	All signals that can be connected to the multiplexer

The following signals and probes can be assigned to a multiplex channel:

signal	MUX	Description
`DATP00`…`DATP06`	0, 1	Direct Analog Test Probes
`RATP00`…`RATP31`	0, 1	Routed Analog Test Probes
`DDTP00`…`DDTP08`	2, 3	Direct Digital Test Probes
`RVREF`	all	Impedance measurement, reference voltage
`RA`	all	Impedance measurement, test voltage
`GND`	all	Ground
`3V3OUT`	all	3.3V power rail
`5VOUT`	all	5.0V power rail

Since the multiplexer only tolerates up to 5V, the following signal probes can be connected or disconnected from the mux:

signal	Description
`DATP00`…`DATP06`	Direct Analog Test Probes
`DDTP00`…`DDTP08`	Direct Digital Test Probes
