Real-Time Clock (RTC_C)
The RTC_C module can be configured for real-time clock (RTC) or 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 runaway 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, and temperature compensation. 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.
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.
Embedded Emulation Module (EEM) (S Version)
The Embedded Emulation Module (EEM) supports real-time in-system debugging. The S version of the EEM
implemented on all devices has the following features:
•
•
•
•
•
Three hardware triggers or breakpoints on memory access
One hardware trigger or breakpoint on CPU register write access
Up to four hardware triggers can be combined to form complex triggers or breakpoints
One cycle counter
Clock control on module level
