OK, I suspect what we want to do is something like...
Send WriteToBuffer command.
Poll for a little while for chips to become ready.
If neither chip is ready, repeat.
If only one chip is ready, abort the WriteToBuffer. Send a zero-length
(or one-byte) buffer and then something other than a WriteConfirm
command, to abort the write. Clear the resulting 'Invalid Command/
Sequence' error bits which will get set, and start again.
