The analog-to-digital (A/D) system in M68HC11 microcontrollers is an
8-channel, 8-bit, multiplexed input converter. It employs a successive
approximation technique with an all-capacitive charge redistribution
system that does not require external sample-and-hold circuits. A/D
converter timing can be synchronized either to the E clock or an internal
resistor-capacitor (RC) oscillator. Separate power supply inputs, AV
and AV
