32bit access ordering on eLBC 16bit bus

[wonderwizard]

If the 8313 performs a 32bit access via a 16bit eLBC two 16bit cycles are performed with incremented addreses.

My question:

write(address, value)

write(0x01000,0xFFAAFF55) #write a 32bit value to address 0x01000

which part of 0xFFAAFF55 is written in the first beat to address 0x01000?

0xFFAA or 0xFF55?

Thanks

Chris

For 0xFFAAFF55 written to address 0x1000, there will be:

0x1000 - 0xFFAA

0x1002 - 0xFF55

[wonderwizard]

0x1002 - 0xFF55

Not 0x1001 - 0xFF55?

Thanks
