UPDATING THE SEQUENCING ENGINE

The major differences between the EEPROM and other
registers are as follows:
way as regular configuration latches. The SE has its own dedicated
512-byte nonvolatile, electrically erasable, programmable, read-
only memory (EEPROM) for storing state definitions, providing
63 individual states, each with a 64-bit word (one state is reserved).

An EEPROM location must be blank before it can be
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 a
At power-up, the first state is loaded from the SE EEPROM into
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 ADM1063 contains a large number of data registers. The
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 ADM1063 (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:
principal registers are the address pointer register and the
configuration registers.

Address Pointer Register
The address pointer register contains the address that selects
one of the other internal registers. When writing to the
ADM1063, 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 ADM1063.
EEPROM
The ADM1063 has two 512-byte cells of nonvolatile EEPROM
from Register Address 0xF800 to Register Address 0xFBFF. The
EEPROM is used for permanent storage of data that is not lost
when the ADM1063 is powered down. One EEPROM cell contains
the configuration data of the device; the other contains the state
performs a user download of Page 0 to Page 6.
SERIAL BUS INTERFACE
The ADM1063 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 ADM1063 to download from its
EEPROM. Therefore, access to the ADM1063 is restricted until
the download is complete.
Identifying the ADM1063 on the SMBus
The ADM1063 has a 7-bit serial bus slave address (see Table 11).
The device is powered up with a default serial bus address.
The five MSBs of the address are set to 00111, and the two LSBs
are determined by the logical states of Pin A1 and Pin A0.
This allows the connection of four ADM1063s to one SMBus.
definitions for the SE. Although referred to as read-only memory,
the EEPROM can be written to, as well as read from, using the
serial bus in exactly the same way as the other registers.
