3.3.1.1.1 SCP_BSY Behavior
The SCP_BSY signal is not part of the SPI protocol, but it is provided so that the slave can signal to the
master that it cannot receive any more data. A falling edge of the SCP_BSY signal indicates the master must
halt transmission. Once the SCP_BSY signal goes high, the suspended transaction may continue. The host
must obey the SCP_BSY pin or control data will be lost.
