5.
The ADC0 subsystem for the C8051F310/1/2/3 consists of two analog multiplexers (referred to collectively
as AMUX0) with 25 total input selections, and a 200 ksps, 10-bit successive-approximation-register ADC
with integrated track-and-hold and programmable window detector. The AMUX0, data conversion modes,
and window detector are all configurable under software control via the Special Function Registers shown
in Figure 5.1. ADC0 operates in both Single-ended and Differential modes, and may be configured to mea-
sure P1.0-P3.4, the Temperature Sensor output, or V
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.
