SMBus PROTOCOLS FOR RAM AND EEPROM
The ADM1063 contains volatile registers (RAM) and nonvola-
tile registers (EEPROM). User RAM occupies Address 0x00 to
Address 0xDF; the EEPROM occupies Address 0xF800 to
The ADM1063 uses the following SMBus write protocols.
Send Byte
In a send byte operation, the master device sends a single
command byte to a slave device, as follows:
Address 0xFBFF.
Data can be written to and read from both the RAM and the
EEPROM as single data bytes. Data can be written only to
unprogrammed EEPROM locations. To write new data to a
programmed location, the location contents must first be erased.
EEPROM erasure cannot be done at the byte level. The EEPROM
is arranged as 32 pages of 32 bytes each, and an entire page
must be erased.

The master device asserts a start condition on SDA.
The master sends the 7-bit slave address followed by the
write bit (low).
The addressed slave device asserts an acknowledge (ACK)
on SDA.
The master sends a command code.
The slave asserts an ACK on SDA.
The master asserts a stop condition on SDA, and the
Page erasure is enabled by setting Bit 2 in the UPDCFG register
(Address 0x90) to 1. If this bit is not set, page erasure cannot
transaction ends.
In the ADM1063, the send byte protocol is used for two purposes:
occur, even if the command byte (0xFE) is programmed across
the SMBus.

To erase a page of EEPROM memory. EEPROM memory
can be written to only if it is unprogrammed. Before writing
to one or more EEPROM memory locations that are already
programmed, the page(s) containing those locations must
first be erased. EEPROM memory is erased by writing a
command byte.
