ADV7611/7612 Map address setting

Hi

We used to use following setting at the biginning of a HDMI EVB script,

and I undersnatnd these Map are programable.

 

98 F4 80 ; CEC                 10000000   
98 F5 7C ; INFOFRAME   01111100
98 F8 4C ; DPLL               01001100      
98 F9 64 ; KSV                  01100100
98 FA 6C ; EDID               01101100
98 FB 68 ; HDMI               01101000
98 FD 44 ; CP                   01000100

 

Are there any limitation/restriction to set Map address on HDMI Rx products?

From above script example, it looks MSB is all set to 0 except CEC, and LSB is all set to 0.

Since LSB of the first address is used for read(0)/write(1), LSB of the Map address setting doesn't take any effect? 

 

A customer is considering to change CP Map address from 0x44 to something else due device address conflict on same I2C line like

98 FD 45 ; CP   not good? same meaning as 0x44

98 FD 46 ; CP   good? 

 

Regards,

Tomoto
