TA1
TA1 is a 16-bit timer/counter (Timer_A type) with three capture/compare registers. TA1 can support multiple
capture/compares, PWM outputs, and interval timing. TA1 also has extensive interrupt capabilities. Interrupts
may be generated from the counter on overflow conditions and from each of the capture/compare registers.

If a different RFCLK divider setting is selected for a radio GDO output, this divider setting is also used for the Timer_A INCLK.
Real-Time Clock (RTC_A)
The RTC_A module can be used as a general-purpose 32-bit counter (counter mode) or as an integrated real-
time clock (RTC) (calendar mode). In counter mode, the RTC_A also includes two independent 8-bit timers that
can be cascaded to form a 16-bit timer/counter. Both timers can be read and written by software. Calendar mode
integrates an internal calendar which compensates for months with less than 31 days and includes leap year
correction. The RTC_A also supports flexible alarm functions and offset-calibration hardware.
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 ADC12_A, LCD_B, and COMP_B modules.
LCD_B (Only CC430F613x and CC430F612x)
The LCD_B driver generates the segment and common signals required to drive a liquid crystal display (LCD).
The LCD_B 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, and 4-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.
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.
