DESCRIPTION
Input/Output Pins — These are the general purpose I/O pins used by the logic
array.
Global Output Enable input pins.
Active Low (0) Reset pin which resets all registers in the device.
Input — Dedicated in-system programming enable pin. This pin is brought low to
enable the programming mode. When low, the MODE, SDI, SDO and SCLK
controls 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/IN 0 also is used
as one of the two control pins for the ISP state machine. When
ispEN
is high, it
functions as a dedicated pin input.

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/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.
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.
