OUT5 ramp current
Ramp current for the delay function. The combination of the number of capacitors and the ramp
current sets the delay full scale.

OUT5 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).
0x0A6

OUT6 delay bypass
Bypasses or uses the delay function.
0: uses delay function.
1: bypasses delay function (default).
0x0A7

OUT6 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.
