Real-Time Clock (RTC_C)
The RTC_C module can be configured for real-time clock (RTC) and calendar mode providing seconds, hours,
day of week, day of month, month, and year. The RTC_C control and configuration registers are password
protected to ensure clock integrity against run away code. Calendar mode integrates an internal calendar that
compensates for months with less than 31 days and includes leap year correction. The RTC_C also supports
flexible alarm functions, offset calibration, temperature compensation and time capture on two external events.
The RTC_C on this device operates on dedicated AUXVCC3 supply and supports operation in LPM3.5.

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. These include the ADC10_A, LCD_C, and SD24_B modules.
the various analog peripherals in the device. These include the ADC10_A, LCD_C, and SD24_B modules.
LCD_C
The LCD_C driver generates the segment and common signals required to drive a liquid crystal display (LCD).
The LCD_C 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, 4-mux, up to 8-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 in static, 2-mux, 3-mux, and 4-mux modes.

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.
