UPDATING THE SEQUENCING ENGINE
Sequencing engine (SE) functions are not updated in the same way
as regular configuration latches. The SE has its own dedicated

registers are as follows:

written to. If it contains data, the data must first be erased.
Writing to the EEPROM is slower than writing to the RAM.
Writing to the EEPROM should be restricted because it has
the engine itself. When the conditions of this state are met, the
next state is loaded from the EEPROM into the engine, and so
on. The loading of each new state takes approximately 10 μs.
To alter a state, the required changes must be made directly to
the EEPROM. RAM for each state does not exist. The relevant
alterations must be made to the 64-bit word, which is then
uploaded directly to the EEPROM.
INTERNAL REGISTERS
The ADM1067 contains a large number of data registers. The
principal registers are the address pointer register and the
a limited write/cycle life of typically 10,000 write operations,
due to the usual EEPROM wear-out mechanisms.
The first EEPROM is split into 16 (0 to 15) pages of 32 bytes
each. Page 0 to Page 6, starting at Address 0xF800, hold the
configuration data for the applications on the ADM1067 (such
as the SFDs and PDOs). These EEPROM addresses are the same
as the RAM register addresses, prefixed by F8. Page 7 is reserved.
Page 8 to Page 15 are for customer use.
Data can be downloaded from the EEPROM to the RAM in one
of the following ways:
configuration registers.

The address point register contains the address that selects one
of the other internal registers. When writing to the ADM1067,
the first byte of data is always a register address that is written to
the address pointer register.
Configuration Registers
The configuration registers provide control and configuration
for various operating parameters of the ADM1067.
EEPROM
The ADM1067 has two 512-byte cells of nonvolatile, electrically
erasable, programmable read-only memory (EEPROM), from
Register Address 0xF800 to Register Address 0xFBFF. The
EEPROM is used for permanent storage of data that is not lost
when the ADM1067 is powered down. One EEPROM cell
contains the configuration data of the device; the other contains
the state definitions for the SE. Although referred to as read-only
performs a user download of Page 0 to Page 6.
SERIAL BUS INTERFACE
The ADM1067 is controlled via the serial system management
bus (SMBus) and is connected to this bus as a slave device
under the control of a master device. It takes approximately
1 ms after power-up for the ADM1067 to download from its
EEPROM. Therefore, access to the ADM1067 is restricted until
the download is complete.
Identifying the ADM1067 on the SMBus
The ADM1067 has a 7-bit serial bus slave address. The device is
powered up with a default serial bus address. The five MSBs of
the address are set to 01111; the two LSBs are determined by the
logical states of Pin A1 and Pin A0. This allows the connection
of four ADM1067s to one SMBus.

using the serial bus in exactly the same way as the other registers.
