LAN Interrupt – Active Low output.
External Reset – input of the system reset. This signal is
active LOW.
Clock Input – 25 MHz external clock or crystal input.
Clock Output – 25 MHz crystal output.
Clock Frequency – define the frequency of the input
clock CLKIN
0 – Clock frequency is 25 MHz.
1 – Reserved.
This input needs to be held low continuously, during and
after reset. This pin should be pulled-down to VSS via a
pull-down resistor.
No Connect
General Purpose Output 2 – General Purpose Output
signal Driven by bits in registers 27 and 31.
