OctoSPI Polling Sends too many bytes

[Robert Sexton]

I've got my OctoSPI interface working for NOR reads and writes, but Auto-polling is sending too many bytes. The Data Length Register (DLR) is set to 0, for one byte of data, but I get the instruction plus two bytes. If I set the DLR to 1, I get three bytes of data.

Configuration snapshot prior to transaction:

5200:5000 20C0:0001 0000:0000 0018:0800 0000:00C7 ..@ ........G...

CR(0x0): FMODE 2 ( Auto Polling Status mode ) + PMM + APMS + EN

SR(0x0):

5200:5040 0000:0000 0000:0000 0000:0000 0000:0000

DLR(0x40) = 0

CCR(0x100) = 1000001 ( 8 bit IR, single lane, single lane DR)
