Description
Bypasses or uses the delay function.
0: uses delay function.
1: bypasses delay function (default).
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.

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).
Description
Sets the output polarity.
