The 4 MSB of the 36 bit SAB address are submitted together with the size field (2 bits). The 4
remaining address bytes are submitted before the number of bytes to read. The size of the
transfer is specified using the values from the following table:
Table 31-44. Size Field Decoding
Below is an example read command:
The length field is set to 0x0007 because there are 7 bytes of additional data: 5 bytes of address
and size and 2 bytes with the number of bytes to read. The address and size field indicates one
word (four bytes) should be read from address 0x500000004.
