peripherals
Peripherals are connected to the CPU through data, address, and control buses and can be handled using all
instructions. For complete module descriptions, see the MSP430x4xx Family User’s Guide, literature number
SLAU056.
digital I/O
There are nine 8-bit I/O ports implemented—ports P1 through P5 and P7 through P10.
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.
D Ports P7/P8 and P9/P10 can be accessed word-wise as ports PA and PB respectively.
D Each I/O has an individually programmable pullup/pulldown resistor.
oscillator and system clock
The clock system in the MSP430x47xx is supported by the FLL+ module, which includes support for a 32768-Hz
watch crystal oscillator, an internal digitally-controlled oscillator (DCO), and a 8-MHz high-frequency crystal
oscillator (XT1), plus a 16-MHz high-frequency crystal oscillator (XT2). The FLL+ clock module is designed to
meet the requirements of both low system cost and low power consumption. The FLL+ features digital
frequency-locked loop (FLL) hardware that, in conjunction with a digital modulator, stabilizes the DCO frequency
to a programmable multiple of the watch crystal frequency. The internal DCO provides a fast turn-on clock
source and stabilizes in less than 6
μs. The FLL+ 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
D ACLK/n, the buffered output of ACLK, ACLK/2, ACLK/4, or ACLK/8
brownout, supply voltage supervisor (SVS)
The brownout circuit is implemented to provide the proper internal reset signal to the device during power on
and power off. The supply voltage supervisor circuitry detects if the supply voltage drops below a user selectable
level and supports both supply voltage supervision (the device is automatically reset) and supply voltage
monitoring (SVM, the device is not automatically reset).
The CPU begins code execution after the brownout circuit releases the device reset. However, VCC may not
have ramped to VCC(min) at that time. The user must ensure the default FLL+ settings are not changed until VCC
reaches VCC(min). If desired, the SVS circuit can be used to determine when VCC reaches VCC(min).
hardware multiplier
The multiplication operation is supported by a dedicated peripheral module. The module performs operations
with 32-bit, 24-bit, 16-bit, and 8-bit operands. The module is capable of supporting signed and unsigned
multiplication as well as signed and unsigned multiply-and-accumulate operations.
watchdog timer (WDT+)
The primary function of the 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.
