Description
b7 b6 b5
MUX_2, MUX_1, MUX_0 - Selection of external input signal or internal signal to be measured at MUX-OUT pin
000
All functions disable. No output voltage at MUX-OUT pin
001
VDD regulator current recopy. Ratio is approx 1/97. Requires an external resistor or selection of Internal 2.0 K (bit 3)
010
Device internal voltage reference (approx 2.5 V)
011
Device internal temperature sensor voltage
100
Voltage at I/O-0. Attenuation or gain is selected by bit 3.
101
Voltage at I/O-1. Attenuation or gain is selected by bit 3.
110
Voltage at VSUP/1 pin. Refer to electrical table for attenuation ratio (approx 5)
111
Voltage at VSENSE pin. Refer to electrical table for attenuation ratio (approx 5)
b4
INT 2k - Select device internal 2.0 kohm resistor between AMUX and GND. This resistor allows the measurement of a voltage proportional
to the VDD output current.
0
Internal 2.0 kohm resistor disable. An external resistor must be connected between AMUX and GND.
1
Internal 2.0 kohm resistor enable.
b3
I/O-att - When I/O-0 (or I/O-1) is selected with b7,b6,b5 = 100 (or 101), b3 selects attenuation or gain
between I/O-0 (or I/O-1) and MUX-OUT pin
0
Gain is approx 2 for device with VDD = 5.0 V (Ref. to electrical table for exact gain value)
Gain is approx 1.3 for device with VDD = 3.3 V (Ref. to electrical table for exact gain value)
1
Attenuation is approx 4 for device with VDD = 5.0 V (Ref. to electrical table for exact attenuation value)
Attenuation is approx 6 for device with VDD = 3.3 V (Ref. to electrical table for exact attenuation value)
Notes
39.
The MUX register can be written and read only when the 5V-CAN regulator is ON. If the MUX register is written or read while
5V-CAN is OFF, the command is ignored, and the MXU register content is reset to default state (all control bits = 0).
