Input/Output Pins - These are the general purpose I/O pins used by the
logic array.
Global Output Enables input pins.
Dedicated input pins to the device.
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.
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/IN0 also is used as one of the two control pins for the isp state
machine. When ispEN is high, it functions as a dedicated input pin.
Input - This pin performs two functions. When ispEN is logic low, it
functions as a pin to control the operation of the isp state machine.
When ispEN is high, it functions as a dedicated input pin.
Output - When ispEN is logic low, it functions as an output pin to read
serial shift register data.
Input - This pin performs two functions. When ispEN is logic low, it
functions as a clock pin for the Serial Shift Register. When ispEN is
high, it functions as a dedicated input pin.
Active Low (0) Reset pin which resets all of the GLB and I/O registers in
the device.
Dedicated Clock input. This clock input is connected to one of the clock
inputs of all the GLBs on the device.
Ground (GND)
