peripherals
Peripherals are connected to the CPU through data, address, and control busses and can be handled using
all instructions. For complete module descriptions, refer to the
MSP430x2xx Family User鈥檚 Guide.
oscillator and system clock
The clock system is supported by the basic clock module that includes support for a 32768-Hz watch crystal
oscillator, an internal very low power, low frequency 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 1
碌s.
The basic clock module provides the following clock signals:
D
Auxiliary clock (ACLK), sourced from a 32768-Hz watch crystal, a high frequency crystal, or the internal very

D
low power LF oscillator.
Main clock (MCLK), the system clock used by the CPU.
Sub-Main clock (SMCLK), the sub-system clock used by the peripheral modules.

brownout
The brownout circuit is implemented to provide the proper internal reset signal to the device during power on
and power off.
digital I/O
There are four 8-bit I/O ports implemented鈥攑orts P1, P2, P3, and P4:
D

D
All individual I/O bits are independently programmable.
Any combination of input, output, and interrupt conditions is possible.
Edge-selectable interrupt input capability for all the eight bits of port P1 and P2.
Read/write access to port-control registers is supported by all instructions.
Each I/O has an individually programmable pullup/pulldown resistor.
WDT+ 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.
