Pin Description
1. NC pins are not to be connected to any active signals, VCC or GND.
2. Pins have dual function capability.
Dedicated Clock inputs. These clock inputs are connected
to one of the clock inputs of all the GLBs on the device.
Active Low (0) Reset pin which resets all of the GLB
registers in 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/Output Pins - These are the general purpose I/O pins
used by the logic array.

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.
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.
Input - This pin performs two functions. When
ispEN is logic
low, it functions as a clock pin for the Serial Shift Register.
