How to use all 4 registers with DS2438?

[raintonr]

The readme for this project says, "The main goal is to use modern sensors (mainly I2C or SPI interface) and transfer their measurements into one or more emulated ds2438 which have 4x16bit registers" but is unclear how to do this.

I note a solution is eluded to here but it's not at all obvous: #83 (comment)

Could we please see alternating between providing VAD & VDD in the DS2438 example?
