MICROCONTROLLER MODES OF OPERATION
The EVAL-ADIN1100EBZ can be used in various modes of opera-
tions implemented in the microcontroller firmware. Up to 16 modes
of operations can be selected by setting the four positions of the
S403 dual inline package (DIP) switch. The status of the switch is
accepted (latched) after the board is powered up or reset.
Therefore, to change the mode of operation, the board must be
reset by pressing the S501 reset button or by applying a power
cycle after changing the position of the S403 DIP switch.
