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.
ADC12_A
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.
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.
USB Universal Serial Bus
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.
Embedded Emulation Module (EEM)
The Embedded Emulation Module (EEM) supports real-time in-system debugging. The L version of the EEM
implemented on all devices has the following features:
• Eight hardware triggers/breakpoints on memory access
• Two hardware trigger/breakpoint on CPU register write access
• Up to ten hardware triggers can be combined to form complex triggers/breakpoints
• Two cycle counters
• Sequencer
• State storage
• Clock control on module level
