MOTOROLA
RESET:
This flag is set when an SPI transfer is complete (after eight SCK cycles in a data transfer). Clear this
flag by reading SPSR, then access SPDR.
This flag is set if the MCU tries to write data into SPDR while an SPI data transfer is in progress. Clear
this flag by reading SPSR, then access SPDR.
Always reads zero
Set when SS is pulled low while MSTR = 1. Cleared by SPSR read followed by SPCR write.
Always read zero
SPI is double buffered in, single buffered out.
SPR[2:0]
0 = No SPI transfer complete or SPI transfer still in progress
1 = SPI transfer complete
0 = No write collision error
1 = SPDR written while SPI transfer in progress
0 = No mode fault error
1 = SS pulled low in master mode
