15.4 USCI Registers: UART Mode
The USCI registers applicable in UART mode are listed in Table 15-6 and Table 15-7.
Table 15-6. USCI_A0 Control and Status Registers
Register Short Form Register Type Address Initial State
USCI_A0 control register 0 UCA0CTL0 Read/write 060h Reset with PUC
USCI_A0 control register 1 UCA0CTL1 Read/write 061h 001h with PUC
USCI_A0 Baud rate control register 0 UCA0BR0 Read/write 062h Reset with PUC
USCI_A0 baud rate control register 1 UCA0BR1 Read/write 063h Reset with PUC
USCI_A0 modulation control register UCA0MCTL Read/write 064h Reset with PUC
USCI_A0 status register UCA0STAT Read/write 065h Reset with PUC
USCI_A0 receive buffer register UCA0RXBUF Read 066h Reset with PUC
USCI_A0 transmit buffer register UCA0TXBUF Read/write 067h Reset with PUC
USCI_A0 Auto baud control register UCA0ABCTL Read/write 05Dh Reset with PUC
USCI_A0 IrDA transmit control register UCA0IRTCTL Read/write 05Eh Reset with PUC
USCI_A0 IrDA receive control register UCA0IRRCTL Read/write 05Fh Reset with PUC
SFR interrupt enable register 2 IE2 Read/write 001h Reset with PUC
SFR interrupt flag register 2 IFG2 Read/write 003h 00Ah with PUC
NOTE: Modifying SFR bits
To avoid modifying control bits of 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.
