Gamma correction base. The desired output for 8*N, where N = 0, .., 31, is programmed into
GAMMAN. Note that data written into these addresses are simultaneously written into
addresses 0xC0 through 0xDF.
The Nth location of the 32 locations is programmed with a 6-bit unsigned number which
represents the gamma correction delta for the gamma bases N and N + 1. The last location
will contain the gamma correction delta for gamma base 31 and presumed base 32 which has
the value of 256. Note that data written into these addresses are simultaneously written into
addresses 0xE0 through 0xFF.
