The ADC subsystem for the C8051F060/1/2/3/4/5/6/7 consists of two 1 Msps, 16-bit successive-approxi-
mation-register ADCs with integrated track-and-hold, a Programmable Window Detector, and a DMA inter-
face (see block diagrams in Figure 5.1 and Figure 5.2). The ADCs can be configured as two separate,
single-ended ADCs, or as a differential pair. The Data Conversion Modes, Window Detector, and DMA
interface are all configurable under software control via the Special Function Registers shown in Figure 5.1
and Figure 5.2. The voltage references used by ADC0 and ADC1 are selected as described in
The ADCs and their respective track-and-hold circuitry can be independently enabled or disabled with the
Special Function Registers. Either ADC can be enabled by setting the ADnEN bit in the ADC’s Control reg-
ister (ADCnCN) to logic 1. The ADCs are in low power shutdown when these bits are logic 0.
