5.
The ADC0 subsystem for the C8051F310/1/2/3/6 consists of two analog multiplexers (referred to collec-
tively 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 measure P1.0–P3.4, the Temperature Sensor output, or V
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.
5.1.
AMUX0 selects the positive and negative inputs to the ADC. Any of the following may be selected as the
positive input: P1.0-P3.4, the on-chip temperature sensor, or the positive power supply (V
following may be selected as the negative input: P1.0-P3.4, VREF, or GND. When GND is selected as
the negative input, ADC0 operates in Single-ended Mode; all other times, ADC0 operates in Differ-
ential Mode. The ADC0 input channels are selected in the AMX0P and AMX0N registers as described in
SFR Definition 5.1 and SFR Definition 5.2.
The conversion code format differs between Single-ended and Differential modes. The registers ADC0H
and ADC0L contain the high and low bytes of the output conversion code from the ADC at the completion
of each conversion. Data can be right-justified or left-justified, depending on the setting of the AD0LJST bit
(ADC0CN.0). When in Single-ended Mode, conversion codes are represented as 10-bit unsigned integers.
