0x0A4 [2:0] OUT7 ramp current Ramp current for the delay function. The combination of the number of capacitors and the ramp
current sets the delay full scale.

0x0A5 [5:0] OUT7 delay fraction Selects the fraction of the full-scale delay desired (6-bit binary).
A setting of 000000 gives zero delay.
Only delay values up to 47 decimals (101111b; 0x2F) are supported (default = 0x00).
0x0A6 0 OUT8 delay bypass Bypasses or uses the delay function.
0: uses delay function.
1: bypasses delay function (default).
0x0A7 [5:3] OUT8 ramp capacitors Selects the number of ramp capacitors used by the delay function. The combination of the
number of capacitors and the ramp current sets the delay full scale.
