8.6.5.9
B Transmit Buffer Status (BTBSTS) — SLIP/MNP4 Mode
Bit 7
Berr – Bus error (set by the CD2231, and cleared by the host)
0 = No bus error.
1 = Bus error was detected on the last transfer.
Bit 6
EOF – End of Frame (set and cleared by the host)
0 = This buffer is not the last in frame/block.
1 = This buffer is the last in frame/block.
Bit 5
EOB – The end of a transmit buffer has been reached
(set by the CD2231, and cleared by the host)
The end of a host supplied transmit buffer has been reached.
Bits 4:2
Reserved – must be ‘0’.
Bit 1
INTR – Interrupt
0 = No interrupt required after the buffer is transmitted.
1 = Interrupt required after the buffer is transmitted.
Bit 0
2231own – Ownership of the transmit buffer (set by the host and cleared by the
CD2231)
0 = Buffer is owned by the host, and not ready for use by the CD2231.
1 = Buffer is owned by the CD2231, and is ready for use by the CD2231.
