16 TCMP2
Set when the timer reaches the comparator 2 value, TCMP2.
15 TCMP1
Set when the timer reaches the comparator 1 value, TCMP1.
14 TCMP0
Set when the Timer reaches the comparator 0 value, TCMP0.
13 TXIDLE
Set when TX goes idle. At this point, transmission has ended
12 CCF
Set when a collision check notices an error in the transmitted data.
11 SSM
Set when the device is selected as a slave when in master mode.
10 MPAF
Set when a multi-processor address frame is detected.
9 FERR
Set when a frame with a framing error is received while RXBLOCK is cleared.
8 PERR
Set when a frame with a parity error (asynchronous mode only) is received while RXBLOCK is cleared.
7 TXUF
Set when operating as a synchronous slave, no data is available in the transmit buffer when the master starts transmission
of a new frame.
6 TXOF
Set when a write is done to the transmit buffer while it is full. The data already in the transmit buffer is preserved.
5 RXUF
Set when trying to read from the receive buffer when it is empty.
4 RXOF
Set when data is incoming while the receive shift register is full. The data previously in the shift register is lost.
