6.9.8
Universal Serial Communication Interface (USCI)
The USCI modules are used for serial data communication. The USCI module supports synchronous
communication protocols like SPI (3-pin or 4-pin), I
2
C, and asynchronous communication protocols like
UART, enhanced UART with automatic baudrate detection, and IrDA.
The USCI_A0 module provides support for SPI (3-pin or 4-pin), UART, enhanced UART and IrDA.
The USCI_B0 module provides support for SPI (3-pin or 4-pin) and I
2
C.
6.9.9
USART1
The hardware universal synchronous/asynchronous receive transmit (USART) peripheral module is used
for serial data communication. The USART supports synchronous SPI (3-pin or 4-pin) and asynchronous
UART communication protocols, using double-buffered transmit and receive channels.
6.9.10 Hardware Multiplier
The multiplication operation is supported by a dedicated peripheral module. The module performs 16×16,
16×8, 8×16, and 8×8 bit operations. The module supports signed and unsigned multiplication as well as
signed and unsigned multiply-and-accumulate operations. The result of an operation can be accessed
immediately after the operands have been loaded into the peripheral registers. No additional clock cycles
are required.
6.9.11 Timer_A3
Timer_A3 is a 16-bit timer/counter with three capture/compare registers. Timer_A3 can support multiple
capture/compares, PWM outputs, and interval timing. Timer_A3 also has extensive interrupt capabilities.
Interrupts may be generated from the counter on overflow conditions and from each of the
capture/compare registers.
