USCI Module

Category

Functional

Function

UART transmit mode with automatic baud rate detection

Description

Erroneous behavior of the USCI_A can occur when configured in UART transmit mode with automatic baud rate detection. During transmission if a "Transmit break" is initiated (UCTXBRK=1), the USCI_A will not deliver a stop bit of logic high, instead, it will send a logic low during the subsequent synch period.

Workaround

1) Follow User's Guide instructions for transmitting a break/synch field following UCSWRST=1.
Or,
2) Set UCTXBRK=1 before an active transmission, i.e. check for bit UCBUSY=0 and then set UCTXBRK=1.
