ADLINK PMC-8246 - Manual (Page 14)

2 Introduction
Watchdog timer (WDT) and bypass control logic circuits are used
to control the relay and communication states. The programmer
can control those functions via the Software Definable Pins (SDP)
on the Intel 82546GB by programming its registers. Please refer to
section 1.5 for a block diagram of the bypass control circuits.
