Comparator_B
The primary function of the Comparator_B module is to support precision slope analog-to-digital conversions,
battery voltage supervision, and monitoring of external analog signals.
ADC10_A
The ADC10_A module supports fast, 10-bit analog-to-digital conversions. The module implements a 10-bit SAR
core, sample select control, reference generator and a conversion result buffer. A window comparator with a
lower and upper limit allows CPU independent result monitoring with three window comparator interrupt flags.
CRC16
The CRC16 module produces a signature based on a sequence of entered data values and can be used for data
checking purposes. The CRC16 module signature is based on the CRC-CCITT standard.
REF Voltage Reference
The reference module (REF) is responsible for generation of all critical reference voltages that can be used by
the various analog peripherals in the device.
LDO and Port U
The integrated 3.3V power system incorporates an integrated 3.3V LDO regulator that allows the entire MSP430
microcontroller to be powered from nominal 5V LDOI when it is made available for the system. Alternatively, the
power system can supply power only to other components within the system, or it can be unused altogether. The
Port U Pins (PU.0/PU.1) function as general-purpose high-current I/O pins. These pins can only be configured
together as either both inputs or bout outputs. Port U is supplied by the LDOO rail. If the 3.3V LDO is not being
used in the system (disabled), the LDOO pin can be supplied externally.
Embedded Emulation Module (EEM) (S Version)
The Embedded Emulation Module (EEM) supports real-time in-system debugging. The S version of the EEM
implemented on all devices has the following features:
•
•
•
•
•
Three hardware triggers/breakpoints on memory access
One hardware trigger/breakpoint on CPU register write access
Up to four hardware triggers can be combined to form complex triggers/breakpoints
One cycle counter
Clock control on module level
