PRODUCTION DATA.
The MSP430AFE2xx devices have one hardware universal synchronous/asynchronous receive transmit (USART0) peripheral module that is used for serial data communication. The USART0 module supports synchronous SPI (3-pin or 4-pin) and asynchronous UART communication protocols, using double-buffered transmit and receive channels. The maximum operational frequency for the USART0 module is 8 MHz.
