Commands are presented by applying a value to the command_code bus and pulsing the command_strobe signal. After a command is presented, the command_busy signal asserts and stays asserted until the command has been queued. Do not present another command until the command_busy signal deasserts. The following table lists all the commands and how to generate them. The following sections describe the commands in detail.
