ADV7513 SPD infoframe checksum

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 [7] =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?
