Description
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 number of the
capacitors and the ramp current sets the delay full scale.

Selects the fraction of the full-scale delay desired (6-bit binary).
000000 gives 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 number of the
capacitors and the ramp current sets the delay full scale.
