LUT (LookUp Table)

Enabling writing the Lookup table
Write the following three commands in sequence.
Address
Data
F0F30000
08004600
F0F30004
0030FFFF
F0F30008
80000000
Disabling writing the Lookup table
Write the following three commands in sequence.
Address
Data
F0F30000
08004600
F0F30004
0030FFFF
F0F30008
00000000
When writing of the Lookup table is enabled, the
addresses 0xF0F60000 to 0xF0F61FFC that store the
Lookup table become open.
The table has two channels. Channel 0 is in EEPROM
write mode, and channel 1 is in RAM write mode.
The table written in EEPROM is read out when Gamma
is set to 3.
The table written in RAM is directly reflected to images
regardless of the Gamma setting.
Channel 0 (EEPROM mode)
Address
Data
F0F60000
Any data
Output data when input data is 0.
F0F60004
Output data when input data is 1.
F0F60008
Output data when input data is 2.
:
:
F0F60FF8
Output data when input data is
0x3FE.
F0F60FFC
Output data when input data is
0x3FF.
Channel 1 (RAM mode)
Address
Data
F0F61000
Any data
Output data when input data is 0.
F0F61004
Output data when input data is 1.
F0F61008
Output data when input data is 2.
:
:
F0F61FF8
Output data when input data is
0x3FE.
F0F61FFC
Output data when input data is
0x3FF.
Although block writing is applicable for either mode,
transfer the next data in EEPROM mode only after
confirming that the previous writing has been
completed, because writing in EEPROM mode requires
a long time.
The common Lookup table is used for both the 16-bit
mode and 8-bit mode. For the 8-bit mode, the most
significant 8 bits of the 10 bits will handle data.
