OUT4 delay bypass
Bypasses or uses the delay function.
0: uses delay function.
1: bypasses delay function (default).
0x0A1
[5:3]
OUT4 ramp capacitors
Selects the number of ramp capacitors used by the delay function. The combination of the
number of the capacitors and the ramp current sets the delay full scale.

OUT4 delay fraction
Selects the fraction of the full-scale delay desired (6-bit binary).
A setting of 000000b gives zero delay.
Only delay values up to 47 decimals (101111b; 0x2F) are supported (default = 0x00).
