MEMORY_READ
The 4 MSB of the 36 bit SAB address are submitted together with the size field (2 bits). Then fol-
lows the 4 remaining address bytes and finally the data bytes. The size of the transfer is
specified using the values from the following table:
Table 31-42. Size Field Decoding
Below is an example write command:
The length field is set to 0x0009 because there are 9 bytes of additional data: 5 address and size
bytes and 4 bytes of data. The address and size field indicates that words should be written to
address 0x500000004. The data written to 0x500000004 is 0xCAFEBABE.
Table 31-43. MEMORY_WRITE Details
This command enables reading of memory/registers on the Service Access Bus (SAB). The
MEMORY_READ command allows words, halfwords, and bytes to be read from a continuous
sequence of addresses in one operation. The user must supply:
