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 LCD_B (Link to User's Guide)
The LCD_B driver generates the segment and common signals that are required to drive a liquid crystal
display (LCD). The LCD_B controller has dedicated data memories to hold segment drive information.
Common and segment signals are generated as defined by the mode. Static, 2-mux, 3-mux, and 4-mux
LCDs are supported. The module can provide a LCD voltage independent of the supply voltage with its
integrated charge pump. It is possible to control the level of the LCD voltage, and thus contrast, by
software. The module also provides an automatic blinking capability for individual segments.
6.12.21 USB Universal Serial Bus (Link to User's Guide)
The USB module is a fully integrated USB interface that is compliant with the USB 2.0 specification. The
module supports full-speed operation of control, interrupt, and bulk transfers. The module includes an
integrated LDO, PHY, and PLL. The PLL is highly flexible and can support a wide range of input clock
frequencies. USB RAM, when not used for USB communication, can be used by the system.
6.12.22 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
