external bootstrap mode. The BL4S100 can be reset from the programming port via the
/RESET_IN
line.
The Rabbit microprocessor status pin is also presented to the programming port. The status
pin is an output that can be used to send a general digital signal.
NOTE: Refer to the Rabbit 4000 Microprocessor User’s Manual for more information
related to the bootstrap mode.
3.3.3 Ethernet Port
Figure 10 shows the pinout for the Ethernet port (J4). Note that there are two standards for
numbering the pins on this connector—the convention used here, and numbering in reverse
to that shown. Regardless of the numbering convention followed, the pin positions relative
to the spring tab position (located at the bottom of the RJ-45 jack in Figure 10) are always
absolute, and the RJ-45 connector will work properly with off-the-shelf Ethernet cables.
ETHERNET
Figure 10. RJ-45 Ethernet Port Pinout
Two LEDs on the RJ-45 Ethernet jack indicate an Ethernet link (green LNK) and Ethernet
activity (yellow ACT).
The grounded RJ-45 connector is shielded to minimize EMI effects to/from the Ethernet
signals.
