Pin description
Fig. 2: Pin description
Table on the left shows the
description for each pin of the
standard LQFP44 package.
The AM512B has two output
modes: parallel output mode
and serial, incremental, linear
output mode. The desired
operational mode can be
selected by pin PS. When the
mode is changed, functions of
some pins are changed.
