(6) Procedure for self-refresh during normal operations
Starting the refresh operation
The following procedure is the procedure used to set cyclic refreshing of the gamma correction and color
shading correction data stored in the built-in RAM during normal operations.
Set the GAM_H1, GAM_H2, GAM_V1 and GAM_V2 registers of the DSD
register and the CSC_HNUM, CSC_VNUM, CSC_HINT and CSC_VINT
registers of the color shading register to the appropriate values.
Start
End
Set GAM_ON and CSC_ON so that the gamma RAMs and color shading
RAMs are used by the video signal.
Set the GAM_ADDR, CSC_ADDR, CSC_SIZE and ROM_TRAN registers
to the addresses and transfer count to be used to perform self-refresh.
Set the REF_RSEL register to gamma RAM (R).
Write "1" to the REF_END register and clear status.
Write 01h to the REF_MODE register and start self-refresh.
Stopping the refresh operation
The following procedure is the procedure used to stop the self-refresh operation.
Start
End
Write 00h to the REF_MODE register to stop self-refresh.
