BUSY
15
0:Ready status
1:Busy status
If it takes time to perform slave side processing,
slave side busy status is announced since reply to
master will be delayed.
In busy status, other response data are unfixed
values. When slave side is busy, request from
master is invalid. Therefore, the same request must
be sent again. During busy status, 0 is returned for
all Bits except for Bit 15.
