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.
shows the MC9S08QE128 Series with the ADC module and pins highlighted.
NOTE
Ignore any references to stop1 low-power mode in this chapter, because the
MC9S08QE128 device does not support it.
10.1.1
ADC Clock Gating
The bus clock to the ADC can be gated on and off using the SCGC1[ADC] bit. This bit is set after any
reset, which enables the bus clock to this module. To conserve power, the ADC bit can be cleared to disable
the clock to this module when not in use. See
Section 5.7, “Peripheral Clock Gating,”
for details.
