(5) Procedure for forced refresh during normal operations
The following procedure is the procedure for selecting either gamma correction or color shading correction
data during normal operations.
During display, mute the video signal using the DSD
register.
Write "1" to the REF_END register and clear status.
Set the GAM_ADDR and ROM_TRAN registers to the
addresses and transfer count to be used to perform
forced refresh.
Start
End
Set GAM_ON = 0 so that the gamma RAMs are not used.
Read the REF_END register.
Set the REF_RSEL register to gamma RAM (R).
Write "1" to the REF_END register and clear status.
Write 02h to the REF_MODE register to start forced
refresh.
Forced refresh complete
for all gamma RAMs.
1: Forced refresh complete
Perform forced
refresh for the other
gamma RAMs.
If a video signal is to be displayed, cancel muting of
the video signal using the DSD register.
Is the status "1"
Read the REF_RSEL register.
Is forced refresh of the
gamma RAMs (R, G, B)
complete
0: Forced refresh
currently being performed
During display, mute the video signal using the DSD
register.
Write "1" to the REF_END register and clear status.
Set the CSC_ADDR, CSC_SIZE and ROM_TRAN
registers to the addresses and transfer count to be
used to perform forced refresh.
Start
End
Set CSC_ON = 0 so that the color shading RAMs are
not used.
Read the REF_END register.
Set the REF_RSEL register to color shading RAM (R).
Write "1" to the REF_END register and clear status.
Write 02h to the REF_MODE register to start forced
refresh.
Set GAM_ON so that the color shading RAMs will be
used by the video signal.
Set GAM_ON so that the gamma RAMs will be used
by the video signal.
Forced refresh complete
for all color shading RAMs.
1: Forced refresh complete
Perform forced
refresh for the other
color shading RAMs.
If a video signal is to be displayed, cancel muting of
the video signal using the DSD register.
Is the status "1"
Read the REF_RSEL register.
Is forced refresh of
the color shading RAMs
(R, G, B) complete
0: Forced refresh
currently being performed
