ISSUE 5
OCTAL SERIAL LINK MULTIPLEXER
1. The logical channel participating in a cell transfer cannot be polled until
nine TCLK periods after the cell transfer is complete.
2. Once the cell transfer is started, the TENB input must remain low until
after the H5/UDF word has been transferred. After that, it is permissible
for TENB to toggle high to momentarily halt the cell transfer.
H5UDF:
The H5UDF bit determines whether or not the H5/UDF octets are included in
cells transferred over the interface. When H5UDF is logic 1 (default), the H5
and UDF octets are included, i.e. the optional “Word 4” illustrated in Fig. 3 (p.
32) is included in the data structure expected on TDAT[15:0].
