I am looking at the ADV7513 programming guide and I have some questions:
Per the HDMI spec the fourth byte of the infoframe is the checksum. The programming guide says that the check sum is automatically calculated if 0x4A  =1.
1. Does packet memory address 0x03 contain the check sum of the SPD?
2. If in auto checksum do I not write to this address?
3. Does the first data field byte, ( first letter of company name) go in 0x03 or 0x04?
