ADVANCE INFORMATION
UART End of Transmission interrupt not set when only TXE is enabled
Rev X
UART End of transmission interrupt(EOT) is not setting when device is set for transmit only (CTL0.TXE = 1). EOT is setting only when both CTL0.TXE and CTL0.RXE are enabled.
Set both CTL0.TXE and CTL0.RXE. You do not need to assign a pin to be the UART receive pin.
