Functional Description
Reading Data from the Receive Output Buffers
When the DSP reads a time slot from an even address in the Receive Output Buffer, the
HDLCU will place it on the LSB byte of the data bus and ‘0’ on the MSB byte. When the
DSP reads a time slot from an odd address, the HDLCU will place it on the MSB byte of
the data bus and ‘0’ on the LSB byte.
Writing Data to the Transmit Input Buffers
When the DSP writes to an even address in the Transmit Input Buffer, the HDLCU will
write the LSB of the data bus. When the DSP writes to an odd address, the HDLCU will
write the MSB byte of the data bus.
