The EEPROM Interface is provided to easily configure the setting without the CPU’s help. Because the EEPROM
Interface is the same as the 93c66, it also allows the CPU to write the EEPROM register and renew the 93c66 at
the same time. After the power up or reset (default value from the hardware pins fetched in this stage), the
Samurai-6M/6MX (ADM6996M/MX) will automatically detect the presence of the EEPROM by reading the address
0 in the 96c66. If the value = 4154
(ADM6996M/MX) will stop loading the 93c66. The user also can pull down the
(ADM6996M/MX) not to load the 93c66. The 93c66 loading time is around 30ms. Then CPU should drive the high-
z value in the EECS,
Samurai-6M/6MX (ADM6996M/MX).
The EEPROM Interface needs only one Write command to complete a “Write” operation to the Samurai-6M/6MX
(ADM6996M/MX). If users would like to update the 93c66 at the same time, then three commands, Write Enable,
Write, and Write Disable, are needed to complete this operation (See 93c66 Spec. for the reference). Users should
note that the EERPOM interface only allows the CPU to write the EEPROM register in the Samurai-6M/6MX
