Major Changes
• Removed Pin 237, P_OUT, from Pinout Table.
• In T_QUEUE_TBL, added clarifications to QUEUE_CREDITS
and AVG_SUB_VALU fields for single DS0 no pointer mode.
• Changed ItypE3 to ItypDS3 in DC Operating Conditions Table.
• Changed the following timing parameters:
• Interrupt Timing: PROC_INTR Tq(max) from 16 ns to 16.5
ns.
