That is config option already. Did you set value? If yes, then there is
driver bug. If not, then add value.

Two clear driver bugs, 1 case unclear and the rest should be programmed
earlier.
So hard code those bugs, if you already didn't, 0x33=0x99, 0x56=0x00,
0xfd=0x46 and make test. Do that same to find out all buggy registers
until it performs as it should.
