Fully Integrated T1/E1 Framer and Line Interface
The Transmit Data Link Controller can be programmed according to the CPU
bandwidth of your system. For systems with 1 CPU dedicated to 1 Bt8370, the
data link status can be polled, and the 64-byte transmit FIFO can be used like a
single byte transmit buffer. For systems where a single CPU controls multiple
Bt8370s, the data link can be interrupt-driven and the entire 64-byte transmit
FIFO can be used to store entire messages. See
high-level description of polling and interrupt-driven Transmit Data Link
Controller software.
