Must be set to "0"
Diagnostics Set to “1”
Smart Mux
If set to “0” it enables short delay for fast operation
If Set to “1” Long Delay recommended for Input References below 150MHz.

Status
Read Only
If EPLOCK reads “0” EEPROM is unlocked. If EPLOCK reads “1”, then the
EEPROM is locked (see Table 4 for how to lock the EEPROM – this can only
be executed once after which the EEPROM is locked permanently).
Status Read Only Always reads “1”
