6.12.15 Comparator_B (Link to User's Guide)
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.
6.12.16 ADC12_A (Link to User's Guide)
The ADC12_A module supports fast 12-bit analog-to-digital conversions. The module implements a 12-bit
SAR core, sample select control, reference generator, and a 16-word conversion-and-control buffer. The
conversion-and-control buffer allows up to 16 independent ADC samples to be converted and stored
without any CPU intervention.
6.12.17 DAC12_A (Link to User's Guide)
The DAC12_A module is a 12-bit R-ladder voltage-output DAC. The DAC12_A may be used in 8-bit or 12-
bit mode, and may be used with the DMA controller. When multiple DAC12_A modules are present, they
may be grouped together for synchronous operation.
6.12.18 CRC16 (Link to User's Guide)
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.
6.12.19 Voltage Reference (REF) Module (Link to User's Guide)
The REF module generates all of the critical reference voltages that can be used by the various analog
peripherals in the device.
6.12.20 LDO and PU Port
The integrated 3.3-V power system incorporates an integrated 3.3-V LDO regulator that allows the entire
MSP430 microcontroller to be powered from nominal 5-V 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 both outputs. Port U is supplied by the LDOO rail. If the 3.3-V
LDO is not being used in the system (disabled), the LDOO pin can be supplied externally.
6.12.21 Embedded Emulation Module (EEM) (Link to User's Guide)
The EEM supports real-time in-system debugging. The L version of the EEM has the following features:
• Eight hardware triggers or breakpoints on memory access
• Two hardware triggers or breakpoints on CPU register write access
• Up to 10 hardware triggers can be combined to form complex triggers or breakpoints
• Two cycle counters
• Sequencer
• State storage
• Clock control on module level
