Dedicated input pins to the device.
Global Output Enable input pins.
Active Low (0) Reset pin which resets all of the GLB registers in the device.
Dedicated Clock inputs. These clock inputs are connected to one of the clock inputs of all
the GLBs on the device.
Input - Dedicated in-system programming enable input pin. This pin is brought low to
enable the programming mode. The TMS, TDI, TDO and TCK options become active.
Input - This pin performs two functions. When
BSCAN
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
BSCAN
is high, it functions as a dedicated input pin.
Input - This pin performs two functions. When
BSCAN
is logic low, it functions as a clock
pin for the Serial Shift Register. When
BSCAN
is high, it functions as a dedicated input pin.
Input - This pin performs two functions. When
BSCAN
is logic low, it functions as pin to
control the operation of the programming state machine. When
BSCAN
is high, it
functions as a dedicated input pin.
Output/Input - This pin performs two functions. When
BSCAN
is logic low, it functions as
the pin to read the isp data. When
BSCAN
is high, it functions as a dedicated input pin.
