CON24 Register The Neon
NEO-8-90 BitFlow, Inc. Version G.5
LUT_HOST_
DATA R/W, CON24[7..0], Alta, Karbon-CL, Karbon-CXP, Neon, R64
This register is used to read and write data from the LUT. The LUT is programmed indi-
rectly using this and the other registers in CON24.
The procedure to write data to the LUT is as follows:
Set LUT_HOST_ACCESS to 1.
Set LUT_DATA_WRITE_SEL to 1.
Set LUT_BANK to the desired bank to program.
Set LUT_HOST_LANE to the desired LUT lane to program.
Set LUT_HOST_ADDR to the desired LUT location to program (LUT input).
Set LUT_HOST_DATA to the value desired (LUT output).
Write LUT_WEN to 1, this copies the value from the LUT_HOST_DATA register to
the LUT’s memory location as specified by LUT_HOST_ADDR.
The procedure to read data from the LUT is as follows:
Set LUT_HOST_ACCESS to 1.
Set LUT_DATA_WRITE_SEL to 0.
Set LUT_BANK to the desired bank to read.
Set LUT_HOST_LANE to the desired LUT lane to read.
Set LUT_HOST_ADDR to the desired LUT location to read.
Read LUT_HOST_DATA, the value returned in this register is the value in the LUT’s
memory.
LUT_ON R/W, CON24[15], Alta, Karbon-CL, Karbon-CXP, Neon, R64
This register is used to insert or bypass the LUT from the path of incoming camera
data.
LUT_HOST_
ADDR R/W CON24[23..16], Alta, Karbon-CL, Karbon-CXP, Neon, R64
This register is used to set the address for a read operation from the LUT memory or a
write operation to the LUT memory. See the description of LUT_HOST_DATA for more
details.
LUT_ON Meaning
0 LUT is not in the data path (bypassed)
1 LUT is in the data path
