CR, Control Register, CR7: CR0

General Purpose Memory Organization, A8:A0
Address: 000h to 1FFh
General Purpose Memory Array Configuration
– last bit of the slave command byte is a R/W bit. The
R/W bit of the Slave Address Byte defines the oper-
ation to be performed. When the R/W bit is a one,
then a read operation is selected. A zero selects a
write operation.
Word Address
The word address is either supplied by the master or
obtained from an internal counter. The internal counter
is undefined on a power-up condition.

Block Protect Option
The device powers-up in the following state:
– The device is in the low power standby state.
– The WEL bit is set to ‘0’. In this state it is not possi-
ble to write to the device.
– SDA pin is the input mode.
– RESET/RESET Signal is active for t PURST .
Slave Address Byte
Following a start condition, the master must output a
Slave Address Byte. This byte consists of several parts:
– a device type identifier that is always ‘101x’. Where
x = 0 is for Array, x = 1 is for Control Register or
Fault Detection Register.
– next two bits are ‘0’.
– next bit that becomes the MSB of the address.

Addressing
Data Protection
The following circuitry has been included to prevent
inadvertent writes:
– The WEL bit must be set to allow write operations.
– The proper clock count and bit sequence is required
prior to the stop bit in order to start a nonvolatile
write cycle.
– A three step sequence is required before writing into
the Control Register to change Watchdog Timer or
Block Lock settings.
