DESCRIPTION
CKIN

I
CLOCK INPUT: Connects to a 25 MHz clock source. This pin should
be held low when XTLP and XTLN are being used as the 25 MHz
clock source.

A
CRYSTAL PINS: Should be connected to a 25 MHz crystal. When
CKIN is being used as the 25 MHz clock source, these pins should be
connected together.
MISCELLANEOUS PINS
GPIO0

I/O
GENERAL PURPOSE I/O PIN: This is an I/O pin which is
configurable as an input or an output via management interface. A
value of one in bit MR16.6 configures GPIO0 as an input, and a zero
configures it as an output. The logic level of the GPIO0 pin is reflected
in MR16.7. This pin has a weak internal pull-down to prevent it from
floating when configured as an input (it is configured as an input by
default).
GPIO1

20
I/O
GENERAL PURPOSE I/O PIN: This is an I/O pin which is
configurable as an input or an output via the management interface. A
value of one in bit MR16.8 configures GPIO1 as an input, and a zero
configures it as an output. The logic level of the GPIO1 pin is reflected
in MR16.9. This pin has a weak internal pull-down to prevent it from
floating when configured as an input (it is configured as an input by
default).
INTR

43
OZ
INTERRUPT PIN: This pin is used to signal an interrupt to the media
access controller. The pin is held in the high impedance state when
an interrupt is not indicated. The pin will be forced high or low to
signal an interrupt depending upon the value of the INTR_LEVEL bt
(MR16.14). The events which trigger an interrupt can be programmed
via the Interrupt Control Register located at address MR17.
