8. 10-Bit ADC (ADC0, C8051T620/6/7 and C8051T320/1 Only)
ADC0 on the C8051T620/6/7 and C8051T320/1 is a 500 ksps, 10-bit successive-approximation-register
(SAR) ADC with integrated track-and-hold, a gain stage programmable to 1x or 0.5x, and a programmable
window detector. The ADC is fully configurable under software control via Special Function Registers. The
ADC may be configured to measure various different signals using the analog multiplexer described in
Section “8.5. ADC0 Analog Multiplexer (C8051T620/6/7 and C8051T320/1 Only)” on page 55. The voltage
reference for the ADC is selected as described in Section “10. Voltage Reference Options” on page 59.
The ADC0 subsystem is enabled only when the AD0EN bit in the ADC0 Control register (ADC0CN) is set
to logic 1. The ADC0 subsystem is in low power shutdown when this bit is logic 0.
