Status EOF:
FIFO Overflow = 0, NRDY = 0
Status EOF:
FIFO Overflow = 0, NRDY = 1
Status EOF:
FIFO Overflow = 1, NRDY = 0
Status EOF:
FIFO Overflow = 1, NRDY = 1
Mark EOF:
EOF for a SYNC frame
Frame EOF:
EOF for a normal data frame
SYNC with DATA Valid:
Says that the next frame will be a SYNC with
DATA frame
Tells the remote transmitter to stop sending data
Tells the remote transmitter it can continue to
send data
IDLE character:
Used as a padding word to maintain receiver
synchronization
