Chip Select
VO8
This pin drives the chip select output of the
external EEPROM.
Note:
The EECS output may tri-state briefly
during power-up. Some EEPROM
devices may be prone to false selection
during this time. When an EEPROM is
used, an external pull-down resistor is
recommended on this signal to prevent
false selection. Refer to your EEPROM
manufacturer’s datasheet for additional
information.
