5.
The ADC0 subsystem for the C8051F34x devices consists of two analog multiplexers (referred to collec-
tively as AMUX0), 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 configured 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 voltages
at port pins, the Temperature Sensor output, or V
tion options for AMUX0 are detailed in SFR Definition 5.1 and SFR Definition 5.2. The ADC0 subsystem is
enabled only when the AD0EN bit in the ADC0 Control register (ADC0CN) is set to logic 1. The ADC0 sub-
system is in low power shutdown when this bit is logic 0.
