Analog-to-Digital Converter (S08ADC12V1)
10.1 Overview
The 12-bit analog-to-digital converter (ADC) is a successive approximation ADC designed for operation
within an integrated microcontroller system-on-chip.
NOTE
MC9S08JM16 series devices operate at a higher voltage range (2.7 V to
5.5 V) and do not include stop1 mode. Therefore, please disregard
references to stop1.
10.1.1 Module Configurations
This section provides information for configuring the ADC on this device.
