The MC68HC912DT128A has two identical ATD modules identified as
ATD0 and ATD1. Except for the V
all pins are duplicated and indexed with ‘0’ or ‘1’ in the following
description. An ‘x’ indicates either ‘0’ or ‘1’.
The ATD module is an 8-channel, 10-bit or 8-bit, multiplexed-input,
successive-approximation analog-to-digital converter. It does not
require external sample and hold circuits because of the type of charge
redistribution technique used. The ATD converter timing can be
synchronized to the system PCLK. The ATD module consists of a 16-
word (32-byte) memory-mapped control register block used for control,
testing and configuration.
