this register cannot be written to; when read, the value is indeterminate.
these bits are set to “000”, with the analog delay circuit selected. However, because these bits can be
read only when SDDS = “1”, the value read from these bits when SDDS = “0” is indeterminate.
only the digital delay value is effective.
amount of delay increases by about 100 ns, so be sure to take this into account when using the device.

In an attempt to write to these bits, write “0”. The value, if read, turns out to be
indeterminate. However, when SDDS = “1”, the value “0” is read out (Note 1)
