memory it responds to the 8 bits received by as-
serting an acknowledge bit during the 9th bit time.
When data is read by the bus master, it acknow-
ledges the receipt of the data bytes in the same
way. Data transfers are terminated with a STOP
condition.
Data in the 4 upper blocks of the memory may be
write protected. The protected area is programma-
ble to start on any 16 byte boundary. The block in
which the protection starts is selected by the input
pins PB0, PB1. Protection is enabled by setting a
Protect Flag bit when the PRE input pin is driven
High.

In
order to prevent data corruption and inadvertent
write operations during power up, a Power On
Reset (POR) circuit is implemented. Untill the V
CC
voltage has reached the POR threshold value, the
internal reset is active: all operations are disabled
and the device will not respond to any command.
In the same way, when V
CC
drops down from the
operating voltage to below the POR threshold
value, all operations are disabled and the device
will not respond to any command. A stable V
CC
must be applied before applying any logic signal.
