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.

USART0
The MSP430AFE2xx devices have one hardware universal synchronous/asynchronous receive transmit
(USART0) peripheral module that is used for serial data communication. The USART0 module supports
synchronous SPI (3 or 4 pin) and asynchronous UART communication protocols, using double-buffered transmit
and receive channels. The maximum operational frequency for the USART0 module is 8 MHz.
Hardware Multiplier
The multiplication operation is supported by a dedicated peripheral module. The module performs 16x16, 16x8,
8x16, and 8x8 bit operations. The module is capable of supporting 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.
SD24_A
The SD24_A module integrates up to three independent 24-bit sigma-delta A/D converters. Each channel is
designed with fully differential analog input pair and programmable gain amplifier input stage. In addition to
external analog inputs, an internal VCC sense and temperature sensor are also available.
