Analog-to-Digital Converter (S08ADC10V1)
14.1
The 10-bit analog-to-digital converter (ADC) is a successive approximation ADC designed for operation
within an integrated microcontroller system-on-chip. The ADC module design supports up to 28 separate
analog inputs (AD0-AD27). Only 9 (AD0-AD3, AD8-AD11, and AD27) of the possible inputs are
implemented on the MC9S08AC16 Series Family of MCUs. These inputs are selected by the ADCH bits.
Some inputs are shared with I/O pins as shown in
for the MC9S08AC16 Series devices are summarized in
14.2
The ADC channel assignments for the MC9S08AC16 Series devices are shown in the table below.
Channels that are unimplemented are internally connected to V
unknown value. Channels which are connected to an I/O pin have an associated pin control bit as shown.
