6.29 UART_ERR_04

UART Module

Category

Functional

Function

Incorrect UART data received with the fast clock request is disabled when clock transitions from SYSOSC to LFOSC

Description

Scenario:
1. LFCLK selected as functional clock for UART
2. Baud rate of 9600 configured with 3x oversampling
3. UART fast clock request has been disabled
If the ULPCLK changes from SYSOSC to LFOSC in the middle of a UART RX transfer, it is observed that one bit is read incorrectly

Workaround

Enable UART fast clock request while using UART in LPM modes.
