flash memory
The flash memory can be programmed via the JTAG port, the bootstrap loader, or in-system by the CPU. The
CPU can perform single-byte and single-word writes to the flash memory. Features of the flash memory include:
D Flash memory has n segments of main memory and two segments of information memory (A and B) of 128
bytes each. Each segment in main memory is 512 bytes in size.
D Segments 0 to n may be erased in one step, or each segment may be individually erased.
D Segments A and B can be erased individually, or as a group with segments 0n.
Segments A and B are also called information memory.
D New devices may have some bytes programmed in the information memory (needed for test during
manufacturing). The user should perform an erase of the information memory prior to the first use.
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.
oscillator and system clock
The clock system in the MSP430x12x 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
μs. 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.
digital I/O
There are three 8-bit I/O ports implemented—ports P1, P2, and P3 (only six port P2 I/O signals are available
on external pins):
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 six bits of port P2.
D Read/write access to port-control registers is supported by all instructions.
NOTE:
Six bits of port P2, P2.0 to P2.5, are available on external pins but all control and data bits for port
P2 are implemented. Port P3 has no interrupt capability.
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.
