Notes
The BSY flag is cleared under any one of the following
conditions: -When the SPI is correctly disabled -When a fault
is detected in Master mode (MODF bit set to 1) -In Master
mode, when it finishes a data transmission and no new data
is ready to be sent -In Slave mode, when the BSY flag is set
to '0' for at least one SPI clock cycle between each data
transfer.
