Legend:

R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’

-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown

bit 7-2

ITRIM<5:0>: Current Source Trim bits

011111 = Maximum positive change (+62% typ.) from nominal current

011110

000001

= Minimum positive change (+2% typ.) from nominal current

000000 = Nominal current output specified by IRNG<1:0>

111111 = Minimum negative change (-2% typ.) from nominal current
