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