FM1288-GE-410

High Performance Voice Processor for Automotive Handsfree

Unspecified 

Summarizing about EEPROM commands:

• The EEPROM commands can be used for boot-up system initialization.

• Data on EEPROM are contiguous bytes that must be organized into a starting dummy byte at

address 0x0000 of the EEPROM, followed by 6-byte EEPROM commands defined above, and then

concluded with an ending indicator of 0xF0 to signal termination of EEPROM command

operations

• The 6-byte commands are each an initialization write either into DM space or into PM space

• The last EEPROM command should be a 6-byte command of writen the value 0x0000 into the DM

address 0x22FB, this is to inform the FM-1288 processor that the last EEPROM command has

been executed

• For writes into the Patch RAM area of the PM space, the rule of setting a specific DM memory

space location at 0x3FCB first, and then clearing it upon done, was descrbed above and must be

followed

System designers using the EEPROM please note the following:

1. Patch RAM initializations are intended for either bug fixes or further functional enhancements to

the on-chip program residing already on ROM. Therefore Patch-RAM write comands, if any, will

be provided by Fortemedia.

2. Data initialization are intended for either affecting the functional behaviors or for improving the

performance via loading specifically tuned parameters over the default ones. Therefore Control

Register and Data write commands, if any, are either provided by Fortemedia or supplied by the

system designer after performing system tuning to obtain optimal parameters. Please also see

“FM-1288 Parameter Tuning Guide” for system tunings.

3. 24C16 is the smallest EEPROM size that the user can use.
