peripherals
Peripherals are connected to the CPU through data, address, and control busses and can be handled using
all instructions. For complete module descriptions, see the MSP430x1xx Family User’s Guide, literature number
SLAU049.
digital I/O
There are six 8-bit I/O ports implemented—ports P1 through P6:
D All individual I/O bits are independently programmable.
D Any combination of input, output, and interrupt conditions is possible.
D Edge-selectable interrupt input capability for all the eight bits of ports P1 and P2.
D Read/write access to port-control registers is supported by all instructions.
oscillator and system clock
The clock system in the MSP430x13x and MSP43x14x(1) family of devices is supported by the basic clock
module that includes support for a 32768-Hz watch crystal oscillator, an internal digitally-controlled oscillator
(DCO) and a high frequency crystal oscillator. The basic clock module is designed to meet the requirements
of both low system cost and low-power consumption. The internal DCO provides a fast turn-on clock source
and stabilizes in less than 6
s. The basic clock module provides the following clock signals:
D Auxiliary clock (ACLK), sourced from a 32768-Hz watch crystal or a high frequency crystal.
D Main clock (MCLK), the system clock used by the CPU.
D Sub-Main clock (SMCLK), the sub-system clock used by the peripheral modules.
watchdog timer
The primary function of the watchdog timer (WDT) module is to perform a controlled system restart after a
software problem occurs. If the selected time interval expires, a system reset is generated. If the watchdog
function is not needed in an application, the module can be configured as an interval timer and can generate
interrupts at selected time intervals.
hardware multiplier (MSP430x14x and MSP430x14x1 Only)
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 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.
USART0
The MSP430x13x and the MSP430x14x(1) have one hardware universal synchronous/asynchronous receive
transmit (USART0) peripheral module that is used for serial data communication. The USART supports
synchronous SPI (3 or 4 pin) and asynchronous UART communication protocols, using double-buffered
transmit and receive channels.
USART1 (MSP430x14x and MSP430x14x1 Only)
The MSP430x14x(1) has a second hardware universal synchronous/asynchronous receive transmit (USART1)
peripheral module that is used for serial data communication. The USART supports synchronous SPI (3 or 4
pin) and asynchronous UART communication protocols, using double-buffered transmit and receive channels.
Operation of USART1 is identical to USART0.
