This is an application note for ADV202 engineering samples that are 0.2(ES3) or higher. It outlines a series of recommended procedures and critical information to confirm correct hardware configuration and initialization of the ADV202. It provides test procedures for direct accesses and indirect accesses, tests to confirm correct DMA interface and JDATA mode operation, and addresses common problems the user may encounter. Performing these specific register access tests facilitates debugging systems for hardware and software errors.
This document provides a series of recommended procedures and critical information to confirm correct hardware configuration and initialization of the ADV202. It covers direct register access functionality, PLL settings, and common problems users may encounter during setup.
The note details specific test procedures for verifying direct accesses, indirect memory read/write operations using DMA interfaces, and JDATA mode operation. It includes step-by-step instructions for 32-bit and 16-bit modes to debug systems for hardware and software errors.

A delay of approximately 20 microseconds is needed after which the ADV202 should undergo a reboot procedure.
Possible causes include incorrect timing or incorrect PLL settings.
