ADM6999U/UX
Data Sheet
Descriptions
The timing for writing to EEPROM is a little bit different. See below graph. Must be carefully when CS goes down
after writting a command, SK must issue at least one clock. This is a difference between ADM6999U/UX with
EEPROM write timing. If system is without EEPROM then users must write ADM6999U/UX internal register by
93C66 timing. If users use EEPROM then the writing timing is depend on EEPROM type.
