2.3.1.1 Power Mode

The Power Control changes the DLPC900 operational mode. When placed into a standby state the system powers down the DMD interface. Enter Standby mode prior to any planned system power shutdowns to safely park the micro-mirrors. Enable Standby mode only after all data for the last frame to be displayed has been transferred to the DLPC900. Standby mode must be disabled prior to sending any new data. See Section 2.3.1.2.

For use cases for Idle Mode, Standby Mode, or DMD Park see Recommended Use Case - Idle Mode, Standby Mode, and Park.

After executing this command, the host may poll the system status using I2C commands 0x20, 0x21, and 0x22 or USB commands 0x1A0A, 0x1A0B, and 0x1A0C to attain status.

0 = Return to Normal mode from Standby Mode of operation. In Normal mode, the selected external source is displayed.
1 = Enter Standby mode to place the DMD in a standby state. Standby disables the front end input data interfaces, parks the DMD array, and powers down parts of the DMD.
Note: Standby mode requires a wait period of two minutes to run 50/50 and park the DMD. Three additional seconds are needed to complete all operations before issuing a Return to Normal command.
Note: Once Standby has been issued the only command accepted by the DLPC900 controller board is Return to Normal (0). Any other command can result in unexpected behavior. Particularly a Park/Unpark is not accepted until Normal mode is resumed.
2 = Perform a software reset
Important: If a software reset is performed in a batch file, no further commands in the batch file are processed resulting in an "idx" (batch file line index number) error. A USB or I2C connection must be established before starting a new batch file.
Note: If a hardware reset is performed while the system is in standby mode the system needs to poll the status again to recognize that normal operation has resumed.
