Dedicated Clock input. This clock input is connected to
one of the clock inputs of all the GLBs on the device.

- Dedicated clock input. This clock input is brought
into the Clock Distribution Network, and can optionally
be routed to any GLB and/or I/O cell on the device.
- Active Low (0) Reset pin which resets all of the GLB
and I/O 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
controls become active.
2
SDI/IN 0
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.

SDO/IN 1
Output/Input — This pin performs two functions. When
ispEN is logic low, it functions as an output pin to read
serial shift register data. When ispEN is high, it
functions as a dedicated input pin.
2
SCLK/Y2
33
27
29
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 clock input. This clock input
is brought into the Clock Distribution Network and
can be routed to any GLB and/or I/O cell on the
device.
