7. 10-Bit ADC (ADC0, C8051F336/8 only)
The ADC0 on the C8051F336/8 is a 200 ksps, 10-bit successive-approximation-register (SAR) ADC with
integrated track-and-hold and programmable window detector. The ADC is fully configurable under soft-
ware control via Special Function Registers. The ADC0 operates in both Single-ended and Differential
modes, and may be configured to measure various different signals using the analog multiplexer described
in
the ADC is selected as described in
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.
