Description
Ramp current for 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).
000000 give zero delay.
Only delay values up to 47 decimals (101111b; 0x2F) are supported.
Bypass or use the delay function.
<0> = 0; use delay function.
<0> = 1; bypass delay function.
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.
