EOFt SEOF Status EOF:
FIFO Overflow = 0, NRDY = 0
EOFdt SEOF Status EOF:
FIFO Overflow = 0, NRDY = 1
EOFa SEOF Status EOF:
FIFO Overflow = 1, NRDY = 0
EOFn SEOF Status EOF:
FIFO Overflow = 1, NRDY = 1
EOFni MEOF Mark EOF:
EOF for a SYNC frame
EOFdti FEOF Frame EOF:
EOF for a normal data frame
R_RDY SWDV SYNC with DATA Valid:
Says that the next frame will be a
SYNC with DATA frame
NOS STOP Tells the remote transmitter to stop
sending data
CLS GO Tells the remote transmitter it can
continue to send data
IDLE IDLE IDLE character:
Used as a padding word to maintain
receiver synchronization
