EEPROM
ADDRESS REGISTER
(ADDR)
The EEPROM Address Register determines the EEPROM location to which an EEPROM access is directed.
As a whole, ADDR auto-increments after read and write cycles to EEPROM, but remains fixed after erase cycles. This
behaviour generates the correct ADDR contents for sequential read accesses and for sequential write or erase/write
accesses with intermediate page setup. Overflow of the 8-bit counter wraps around to zero.

TEST REGISTER
(TST)
The EEPROM Test register is used for testing purposes during device manufacture. It must not be accessed by the
device user.

DESCRIPTION
7
This bit is set to a logic 0.
AD2 to AD6 select one of 32 pages.
AD1 and AD0 are irrelevant during erase and write cycles. For read accesses, AD0 and
AD1 indicate the byte location within an EEPROM page. During page setup, finally, AD0
and AD1 select EEPROM Latch 0 to 3 whereas AD2 to AD6 are irrelevant. If increment
mode (Table 12) is active during page setup, the subcounter consisting of AD0 and AD1
increments after every write to an EEPROM latch, thus enhancing access to sequential
EEPROM latches. Incrementing stops when EEPROM Latch 3 is reached, i.e. when
AD0 and AD1 are both a logic 1.

DESCRIPTION

D7 to D0
The EEPROM Data Register (DATR) is only a conceptual entity. A read operation from
DATR, reads out the EEPROM byte addressed by ADDR. On the other hand, a write
operation to DATR, loads data into the EEPROM latch (see Fig.5) defined by bits AD0
and AD1 of ADDR.
