Universal Serial Communication Interface (USCI)

The USCI modules on the MSP430 support multiple serial communication modes. Different USCI modules support different modes. Each different USCI module is named with a different letter. For example, USCI_A is different from USCI_B, etc. If more than one identical USCI module is implemented on one device, those modules are named with incrementing numbers. For example, if one device has two USCI_A modules, they are named USCI_A0 and USCI_A1. See the device-specific data sheet to determine which USCI modules, if any, are implemented on which devices.
USCI_Ax modules support:
- UART mode
- Pulse shaping for IrDA communications
- Automatic baud-rate detection for LIN communications
- SPI mode
USCI_Bx modules support:
- I2C mode
- SPI mode
