7.
The ADC2 subsystem for the C8051F060/1/2/3 consists of an analog multiplexer (referred to as AMUX2),
and a 200 ksps, 10-bit successive-approximation-register ADC with integrated track-and-hold and pro-
grammable window detector (see block diagram in Figure 7.1). The AMUX2, data conversion modes, and
window detector can all be configured from within software via the Special Function Registers shown in
Figure 7.1. ADC2 operates in both Single-ended and Differential modes, and may be configured to mea-
sure any of the pins on Port 1, or the Temperature Sensor output. The ADC2 subsystem is enabled only
when the AD2EN bit in the ADC2 Control register (ADC2CN) is set to logic 1. The ADC2 subsystem is in
low power shutdown when this bit is logic 0.
