DESCRIPTION

In the GC register (LIUs 9–16), changed bit 7 from Reserved to RIMPMS and

changed bit 2 from Reserved to CALEN (see also page 44, Table 6-5).

For TST, changed bits 7, 6, and 5 from Reserved to JABWS1, JABWS0, and

RHPMC.

In the bit 7 (RIMPON) description, changed GC.RTCTL to TST.RHPMC; added note

to bit description.

Changed bit description for OE bits 7 to 0.

For EZDE, corrected bit names for LIUs 1–16 from EXZDE[1:16] to EZDE[1:16];

changed bit description to say “Excessive zero detection is only relevant when

HDB3 or B8ZS decoding is enabled.” For CVDEB, changed bit description to say

“Code violation detection is only relevant when HDB3 decoding is enabled (LCS

register).”

In Table 12-1, deleted “Power Dissipation in Package”; added new Table 12-2.

Package Power Dissipation (for Thermal Considerations) and Table 12-3. Per-

Channel Power-Down Saving (for Thermal Considerations).

Added note to bit 3 (RSMM1:RSSM4) description and updated descriptions for bits

6–4 and 2–0 (deleted “When” from each sentence for clarity).

Updated package drawing information.

Table 8-3: added “Note 1: Specifications to -40°C are guaranteed by design (GBD)

and not production tested.”

Table 9-3, 9-4, 9-5, 9-6: added “Note 1: The timing parameters in this table are

guaranteed by design (GBD).”
