Table 5-3. XRC Register Access Pins, 8 pins
Activity Out. These pins, synchronous to the 50 MHz clock, represent the
activities of each port and also serve as data framing signals for the packet
on EDATA. ACT_P leads EDAT's /J/K pattem by more than 80ns and is
deasserted 40 ns after the /T/R or the last byte of Jam patterns.
Partition/Link Good. This pin, active high, shows the Patition and Link
status of the repeater MX98741. The serial input data is stored in Register
RS[12:1]=081h.
JAB/Elastic Buffer Over/Underflow. This pin, active high, shows the Jabber
status and Elastic Buffer Over/Underflow status of the XRC. The serial input
data is stored in Register RS[12:1]=01Ah.
Isolation. This pin shows the Isolation status of the XRC. The serial input
data is stored in Register RS[12:1]=01Ch.
