4450 – Data Sheet, DS-0131-06
Page 61
Hifn Confidential
When the network ports are connected to a fiber optic PHY or an SFP module, the
Transmitter Enable (TX EN) and Signal Detect (SigDet) signals from the PHY may be
connected to the 4450 so that the optional Station Management (STM) software can
manage these signals. There are two GPIO's assigned to this function for Network port 0
and two more for Network port 1.
Note that within the 4450, these signals have no direct impact on the data flow through the
device. The SigDet signal(s) are simply monitored by the STM server and the state reported
to the host. The TX EN signal(s) are driven out to the PHY by the STM server under
command of the host.
Other GPIO Functionality (Optional)
Some of the remaining GPIO pins may have other Primary or Secondary (Reset Capture)
uses defined after reset. Additional information on alternate functionality of the GPIO pins
will be provided on a subsequent release of the data sheet.
