3.15 J606 Write Protection of SPI EEPROM
Various types of SPI EEPROM devices can populate space U607.
Some of these devices provide a write protection function
3
. Closing
Jumper J606 connects pin 3 of the serial EEPROM with GND and
thus activates write protection.
The following configurations are possible:
Write Protection EEPROM J606
Write protection of EEPROM deactivated open*
Write protection of EEPROM activated closed
* = Default setting

: Should only be used if CAN transceivers U605 and U606 are populated.
2
: Note! Should only be used if CAN transceivers U605 and U606 are NOT populated.
