MC68HC708MP16 Datasheet, PDF (359/398 Pages) Freescale Semiconductor, Inc – Microcontrollers

Analog-to-Digital Converter (ADC)
19.7.5 ADC Voltage Reference Low Pin (V_REFL)
V_REFL is the lower reference supply for the ADC. Connect the V_REFL pin
to the same voltage potential as V_SSAD.
19.7.6 ADC Voltage In (ADVIN)
ADVIN is the input voltage signal from one of the 10 ADC channels to
the ADC module.
19.8 I/O Registers
The following I/O registers control and monitor operation of the ADC:
• ADC status and control register (ADSCR)
• ADC data register (ADR)
• ADC clock register (ADCLK)
