Dedicated input pins to the device
Global Output Enable input pins
Active Low (0) Reset pin which resets all the registers in the device.
Dedicated Clock input. This clock input is connected to one of the clock
inputs of all the GLBs in the device.
Input
—
Dedicated in-system programming Boundary Scan enable input
pin. This pin is brought low to enable the programming mode. The TMS,
TDI, TDO and TCK controls become active.
Input
—
This pin performs two functions. When
ispEN
is logic low, it
functions as a serial data input pin to load programming data into the
device. 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 ISP/Boundary Scan 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 mode control pin for the ISP/Boundary Scan 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.
