Description
/SCAN_TRST
167
In
NA
Scan Test Reset is an active low signal for boundary scan logic.
NOTE: When not using boundary scan, connect this pin to
ground. /SCAN_TRST has an internal pull-up resistor.
SCAN_TMS

Scan Test Mode Select is the mode select signal for boundary scan
logic.

Process Test is an output to measure process test parameters only
during device manufacture. Leave unconnected during normal
operation.
PULLUP_DISABLE
238
In
NA
Pullup Disable is used to disable internal pullup resistors during
manufacturing tests. Connect directly to ground.
*Present when /RESET is asserted and SYS_CLK is being clocked.
**All input (In) and bidirectional (Bi) signals are pulled up through a large, internal pull-up resistor.
