SPI Busy/Ready Status
The busy/ready status must always be checked to confirm the Ready status prior to any read operation.
The Busy status is asserted as soon as a valid opcode is received. The Ready status is asserted when both the
instruction buffer and trace buffer are empty. If the uM-FPU is Ready the SOUT pin is held Low. If the uM-FPU is
Busy, either executing instructions, or because the debug monitor is active, the SOUT pin is held High. The
minimum data period must have elapsed since the last byte was transmitted before the SOUT status is checked. If
more than 32 bytes of data are sent between read operations, the Ready status must also be checked at least once
every 32 bytes to ensure that the instruction buffer does not overflow.
