PTYP
PTYP:
The Parity Type (PTYP) bit selects even or odd parity for the RPRTY output.
When set to logic 1, RPRTY completes even parity bit for RDAT[15:0]. When
set to logic 0, RPRTY completes odd parity bits for RDAT[15:0].
PREPEND:
The PREPEND bit determines whether a word is prepended to each cell.
When PREPEND is logic 1, the optional “Word 1” illustrated in Fig. 3 (p. 34)
is included in the data structure presented on RDAT[15:0].
Reserved:
This bit must be logic 0 for correct operation.
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 presented on RDAT[15:0].
INADDUDF:
The INADDUDF (inband addressing in UDF byte) bit re-locates the inband
address. When this bit is set, the logical channel address for in band
selection is located in the fourteen lower bits of the H5 and UDF bytes and
there is no extended address word in front of the prepend word. This bit
supercedes the H5UDF bit, in that it forces the inclusion of “Word 4”. This bit
has no effect if the RANYPHY input is logic 1.
