Table 55. Fine Delay Adjust—OUT6 to OUT9
Reg.
Addr.
(Hex) Bits Name Description
0x0A0 0 OUT6 delay bypass Bypasses or uses the delay function.
0: uses delay function.
1: bypasses delay function (default).
0x0A1 [5:3] OUT6 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.

0x0A2 [5:0] OUT6 delay fraction 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).
0x0A3 0 OUT7 delay bypass Bypasses or uses the delay function.
0: use delay function.
1: bypass delay function (default).
0x0A4 [5:3] OUT7 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.
