6.11.22 Real-Time Clock (RTC_C) (Link to User's Guide)
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.
6.11.23 REF Voltage Reference (Link to User's Guide)
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.
6.11.24 LCD_C (Link to User's Guide)
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.
6.11.25 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.
