VREF Module

Category

Functional

Function

Switch VREF from 2.5V to 1.4V mode has a very low slew rate

Description

VREF configuration change from 2.5V to 1.4V mode has a very slow slew rate.

Workaround

Use the below procedure to switch VREF mode. 1.Disable VREF by using the ENABLE bit in the CTL0 register before changing configuration to 1.4V mode. 2.Configure pin PA23(VREF+) as GPIO output and drive this pin to logic low for 100us. A 1uF external capacitor is assumed on the VREF+ pin 3.Re-enable VREF in 1.4V by setting the BUGCONFIG bit in the CTL0 register to 1. With this procedure, the time required to switch from 2.5V to 1.4V mode is 200us.
