Introduction
The ATD is an 8-channel, 10-bit, multiplexed-input
successive-approximation analog-to-digital converter, accurate to ±2
least significant bits (LSB). It does not require external sample and hold
circuits because of the type of charge redistribution technique used. The
ATD converter timing is synchronized to the system P clock. The ATD
module consists of a 16-word (32-byte) memory-mapped control register
block used for control, testing and configuration.
