Bit Name Bit No. Description
SCFI [3:0] Sink current fade-in time. Note that the fade time given is from zero to full scale (the actual full-scale value is affected
by the LEVEL_SET bits). Binary code fade-out times are as follows:
0000 = disabled.
0001 = 0.05 sec.
0010 = 0.10 sec.
0011 = 0.15 sec.
0100 = 0.20 sec.
…
1111 = 1.75 sec.
