5.  Using the UPMP-F960-EMIF with the UDP Motherboard

5.1.  VBAT Selector Switch

When used with the UDP motherboard, the motherboard can power the UPMP-F960-EMIF MCU card. With the
VBAT selector switch in the VREG position, the motherboard powers the regulator on the card. With the VBAT
selector switch in the UDP position, the UDP motherboard powers VBAT directly. This position supports software
control of the variable voltage power supply and current measurements.

The S1 switch on the UDP motherboard selects between the fixed or programmable voltage. The variable supply is
controlled by the C8051F384 board control MCU through the U1 digital potentiometer. Use the fixed supply when
the variable supply is not under software control.

5.2.  Current Measurement

The power measurement circuitry on the UDP motherboard consists of a Silicon Labs C8051F351 8051 MCU that
measures both input voltage and current consumption of the MCU card, I/O expander, and radio card. When using
the VBAT selector in the UDP position, install a shorting block on the UDP Motherboard J13 connecting the two left
pins together.
