The hardware clears this bit either when the host “set configuration value” is zero or
UDC receives a reset signal.
User must save the Port 5 input pin state before enabling the Port 5 wake-up function.

SPI Read Overflow bit
0 = No overflow
1 = A new data is received while the previous data is still being held in the
SSE SPI Shift Enable bit
0 = Reset as soon as the shifting is complete, and the next transmission is
1 = Start to shift, and keep at 1 while the current transmission is still being
0 = Receiving not completed yet, and SPIRB has not fully exchanged.
1 = Receiving completed; SPIRB is fully exchanged.

Set Configuration flag. Read only; set when the value of “set configuration”
command is a non-zero.
SPIB register. In this situation, the data in the SPIS register will be
destroyed. To avoid setting this bit, users should better read the SPIRB
register even if only transmission is implemented.

transmitted.
This bit will reset to 0 at every transmission by the hardware
This can only occur in slave mode.
This bit is valid in master mode.
