GOE 0/IN 43
This is a dual function pin. It can be used either as Global Output Enable for
all I/O cells or it can be used as a dedicated input pin.

Input - Dedicated in-system programming enable input pin. This pin is
brought low to enable the programming mode. The MODE, SDI, SDO and
SCLK options become active.
SDI/IN 02
25
Input - This pin performs two functions. When ispEN is logic low, it functions
as an input pin to load programming data into the device. SDI/IN 0 is also
used as one of the two control pins for the isp state machine. It is a
dedicated input pin when ispEN is logic high.
Input - This pin performs two functions. When ispEN is logic low, it functions
as pin to control the operation of the isp state machine. It is a dedicated
input pin when ispEN is logic high.

Output/Input - This pin performs two functions. When ispEN is logic low, it
functions as an output pin to read serial shift register data. It is a dedicated
input pin when ispEN is logic high.
Input - This pin performs two functions. When ispEN is logic low, it functions
as a clock pin for the Serial Shift Register. It is a dedicated input pin when
ispEN is logic high.
Active Low (0) Reset pin which resets all of the GLB and I/O registers in the
device.
