Message Byte:
0x01: Block Message Followed by data
0x00: End of Data stream
Length:
Number of blocks to be read (add data)
(For example above, Length would be 0009h)
Device Address:
Chip Address of ADAV4601
Address:
Target Memory address in ADAV4601
Data :
Data to be written
Message Byte:
0x01: Block Message Followed by data
0x00: End of Data stream
Boot Time
The EEPROM has 4 blocks which need to be copied to the part.
•
SigmaDSP program 3072 x 6 bytes = 18432 bytes
•
SigmaDSP parameters 1024 x 4 bytes = 4096 bytes
•
Application layer instructions 640 x 5 bytes = 3200 bytes
•
Application layer lookup table 6144 x 4 bytes = 24567 bytes
The time given to copy each block is given below:
