Analog-to-Digital Converter (ADC16)
21.1.3
The ADC is capable of performing conversions by using the MCU bus clock, the bus clock divided by two,
the local asynchronous clock (ADACK) in the module, or the alternate clock (ALTCLK). The ALTCLK
on the MCF51EM256 series is connected to the ICSERCLK.
21.2
The MCF51EM256 series each includes four separately controllable ADCs. Assignment of device ADC
pins is spread over each of the available ADCs as shown in
