timer_B3
Timer_B3 is a 16-bit timer/counter with three capture/compare registers. Timer_B3 can support multiple
capture/compares, PWM outputs, and interval timing. Timer_B3 also has extensive interrupt capabilities.
Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare
registers.

universal serial communications interface (USCI)
The USCI module is used for serial data communication. The USCI module supports synchronous
communication protocols like SPI (3 or 4 pin), I
2
C and asynchronous communication protocols such as UART,
enhanced UART with automatic baudrate detection (LIN), and IrDA.
USCI_A0 provides support for SPI (3 or 4 pin), UART, enhanced UART, and IrDA.
USCI_B0 provides support for SPI (3 or 4 pin) and I
2
C.

ADC10
The ADC10 module supports fast, 10-bit analog-to-digital conversions. The module implements a 10-bit SAR
core, sample select control, reference generator and data transfer controller, or DTC, for automatic conversion
result handling allowing ADC samples to be converted and stored without any CPU intervention.
operational amplifier OA (MSP430x22x4 only)
The MSP430x22x4 has two configurable low-current general-purpose operational amplifiers. Each OA input
and output terminal is software-selectable and offer a flexible choice of connections for various applications.
The OA op amps primarily support front-end analog signal conditioning prior to analog-to-digital conversion.
