9.10.2 Transmit HDLC Controller
9.10.2.1
The Transmit HDLC FIFO Buffer Available Register (TFBA) indicates the number of bytes that can be written into
the transmit FIFO. The count form this register informs the host as to how many bytes can be written into the
transmit FIFO without overflowing the buffer. This is a real-time register. The count shall remain valid and stable
during the read cycle.
9.10.2.2
The HDLC status registers in the DS26518 allow for flexible software interface to meet the user’s preferences.
When transmitting HDLC messages, the host can choose to be interrupt driven, or to poll to desired status
registers, or a combination of polling and interrupt processes can be used.
for using the DS26518 HDLC receiver.
