Hello,
the datasheet Rev. B states in section 16.6 (UART/Register description):
| Note: The UARTCTL register should not be changed while the UART is enabled or else the results
| are unpredictable.
Does this include the RTS bit (#11)
| 11 RTS RW 0 Request to Send When RTSEN is clear, the status of this bit is reflected on the U1RTS, signal. If RTSEN is set, this bit is ignored on a write and should be ignored
too? E.g. have I to disable the UART before I can change RTS, or is this allowed while UART is running? (RTSEN is off).
