A little bit different with the timing on writing EEPROM. See below graph. Must be
carefully is when CS go down after write a command, SK must issue at least one clock.
This is a difference between ADM6995L with EEPROM write timing. If system without
EEPROM then user must write ADM6995L internal register by 93C66 timing. If user
uses EEPROM then the writing timing is depend on EEPROM type.
