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. It is a
dedicated input pin when ispEN is logic high. When
ispEN is logic low , it functions as an input pin to load
programming data into the device. SDI/IN 0 also is
used as one of the two control pins for the isp state
machine.
Input – This pin performs two functions. It is a
dedicated input pin when ispEN is logic high. When
ispEN is logic low, it functions as a pin to control the
operation of the isp state machine.
Input/Output – This pin performs two functions. It is a
dedicated input pin when ispEN is logic high. When
ispEN is logic low, it functions as an output pin to read
serial shift register data.
Input – This pin performs two functions. It is a
dedicated clock input when ispEN is logic high. 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. When ispEN is logic low,
it functions as a clock pin for the Serial Shift Register.
Dedicated Clock input. This clock input is connected
to one of the clock inputs of all of the GLBs on the
device.
This pin performs two functions:
–Dedicated clock input. This clock input is brought
into the Clock Distribution Network, and can
optionally be routed to any GLBand/or I/O
cellon the device.
–Active Low (0) Reset pin which resets all of the
GLB and I/O registersin the device.
