SPI Busy
0 = Transmit or Receive is completed
1 = Transmit or Receive is in process
Transmission End Interrupt Source flag
0 = Automatically resets to '0' when firmware reads this
register
1 = Automatically sets to '1' when transmission end occurs
Receive Overrun Interrupt Source flag
0 = Automatically resets to '0' when firmware reads this
register
1 = Automatically sets to '1' when receive overrun occurs
Transfer Interrupt Source flag
0 = Automatically resets to '0' when SPITDR is full (just after
the SPITDR is written)
1 = Automatically sets to '1' when SPITDR is empty (just after
byte loads from SPITDR into SPI shift register)
Receive Interrupt Source flag
0 = Automatically resets to '0' when SPIRDR is empty (after
the SPIRDR is read)
1 = Automatically sets to '1' when SPIRDR is full
