Usart Registers: Spi Mode - Texas Instruments MSP430x4xx User Manual

15.3 USART Registers: SPI Mode

Table 15−1 lists the registers for all devices implementing a USART module.
Table 15−2 applies only to devices with a second USART module, USART1.
Table 15−1.USART0 Control and Status Registers
Register
USART control register
Transmit control register
Receive control register
Modulation control register
Baud rate control register 0
Baud rate control register 1
Receive buffer register
Transmit buffer register
SFR module enable register 1
SFR interrupt enable register 1
SFR interrupt flag register 1
Table 15−2.USART1 Control and Status Registers
Register
USART control register
Transmit control register
Receive control register
Modulation control register
Baud rate control register 0
Baud rate control register 1

Note: Modifying the SFR bits
To avoid modifying control bits for other modules, it is recommended to set
or clear the IEx and IFGx bits using BIS.B or BIC.B instructions, rather than
MOV.B or CLR.B instructions.
