Chapter 10
Analog-to-Digital Converter (S08ADC12V1)
10.1 Introduction
The 12-bit analog-to-digital converter (ADC) is a successive approximation ADC designed for operation
within an integrated microcontroller system-on-chip.
NOTE
MC9S08DZ128 Series devices operate at a higher voltage range (2.7 V to
5.5 V) and do not include stop1 mode. Please ignore references to stop1.
The ADC channel assignments, alternate clock function, and hardware trigger function are configured as
described in Section 10.1.1, “Channel Assignments.”
10.1.1
Channel Assignments
NOTE
The ADC channel assignments for the MC9S08DZ128 Series devices are
shown in Table 10-1. Reserved channels convert to an unknown value.
This chapter shows bits for all S08ADC12V1 channels. MC9S08DZ128
Series MCUs do not use all of these channels. All bits corresponding to
channels that are not available on a device are reserved.
10.1.2 Analog Power and Ground Signal Names
References to V_DDAD and V_SSAD in this chapter correspond to signals V_DDA and V_SSA, respectively.
