The ADC interface has two general-purpose signals,
. The evaluation board with which the extender interfaces

direction and the source of these signals, refer to

The ADC interface connects to the PDAP of the ADSP-21262 processor.
The PDAP is multiplexed with the address and data bus. To avoid bus
contention with the memory devices on the EZ-KIT Lite, the driver con-
nected to the data bus of the ADC must be enabled. For more information
about enabling the data bus, see

DIP Switches and Jumpers

The following section describes the function of all of the jumpers and
switches on the EZ-Extender. Before connecting the extender, familiarize
yourself with each possible setting's effect on your application.

Direction/Clock Source Control Switch (SW1)

A designated DIP switch,
