UCA1STAT&UCRXERR

UCA1STAT and UCRXERR are two registers in the MSP430 microcontroller.

UCA1STAT is the USART Control Register A1 Status Register. It contains status information about the USART communication, such as the state of the transmit and receive buffers, the status of the transmission and reception, and the state of the USART interrupt flag.

UCRXERR is the USART Receive Error Register. It contains information about the errors that occurred during the reception of data, such as framing errors, parity errors, and overrun errors.

Together, these registers provide important information about the status of the USART communication and any errors that may have occurred during the reception of data
