6.11.20 Shared Reference (REF_A)
The reference module (REF_A) is responsible for generation of all critical reference voltages that can be
used by the various analog peripherals in the device.
6.11.21 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, and 2-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.
6.11.22 Embedded Emulation
6.11.22.1 Embedded Emulation Module (EEM)
The EEM supports real-time in-system debugging. The S version of the EEM that is 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
6.11.22.2 EnergyTrace++™ Technology
The devices implement circuitry to support EnergyTrace++ technology. The EnergyTrace++ technology
allows you to observe information about the internal states of the microcontroller. These states include the
CPU Program Counter (PC), the ON or OFF status of the peripherals and the system clocks (regardless of
the clock source), and the low-power mode currently in use. These states can always be read by a debug
tool, even when the microcontroller sleeps in LPMx.5 modes.
The activity of the following modules can be observed:
• MPY is calculating.
• WDT is counting.
• RTC is counting.
• ADC: a sequence, sample, or conversion is active.
• REF: REFBG or REFGEN active and BG in static mode.
• COMP is on.
• eUSCI_A0 is transferring (receiving or transmitting) data.
• eUSCI_A1 is transferring (receiving or transmitting) data.
• eUSCI_B0 is transferring (receiving or transmitting) data.
• eUSCI_B1 is transferring (receiving or transmitting) data.
• TB0 is counting.
• TA0 is counting.
• TA1 is counting.
• TA2 is counting.
• TA3 is counting.
• LCD: timing generator is active.
