As the figure above shows, the LED report can be easily implemented. Each of the port status report
pins outputs the port status and is sequentially latched by an external IC at the rising edge of the
M0
3 pulse.
In the TP link/activity report section, a low output from TP0
10RPT and BTPRPT indicates that the
TP ports and the
extension port
are in link good state. A high output indicates that the TP ports and
extension port
are not in link good state, and the LED is lit. If a data frame is passing through the port,
a 10 Hz signal with a half duty cycle is output to flash the LEDs through a driving circuit to show that
the TP port is receiving packets. Note that when the TP ports have incoming packets, the link/activity
signal is still reported even if the ports are partitioned or disabled.
In the partition status report section, a high output from TP0
10RPT means the traffic on each
FastMPR port connected to a network segment or a node is flowing smoothly. A low output on
TP0
10RPT means the TP ports are in the partition state, and BTPRPT is undefined during this time.
In this mode, the LED will be kept on when a port is partitioned.
In the network utilization report status section, TP0
9RPT will output the network utilization status,
and the TP10RPTand BTPRPT pins are undefined. The Winbond FastMPR uses a proprietary
technique to smoothly control the network utilization display, which is usually handled by the CPU.
The FastMPR counts every bit, including preamble, runt packets, and so on, running over the media,
so that it can display practical information on network utilization. It samples this counted value every
40 mS to determine which LEDs should be lit, so that the LED will be lit on or off in a smooth and
ordering fashion. The relationship between utilization and the LEDs is described in the table below.
In the jabber status report section, a low output from the TPnRPT (n = 0, 1, ..., 10) pins indicates the
TP ports are in the jabber state. A high output indicates the TP ports are not in the jabber state. At
this time, BTPRPT has no function. When the
extension port
is disabled, the output behavior of
BTPRPT will be the same as that of TP0
10RPT.
The pin/utilization report combinations are shown in the following table:
