General Purpose I/O pins. Connected to an
internal register, so customer can set
user-defined parameters. Bits [4:0] reserved
at startup or reset for memory Tapped Delay
Line (TDL) setup. See the ZL50110/11/12/14
Programmers Model for more details.
Recommend 5 kohm pulldown on these
signals.
Test Mode input - ensure these pins are tied
to ground for normal operation.

JTAG Reset. Asynchronous reset. In normal
operation this pin should be pulled low.
Recommend external pull-down.
JTAG Clock - maximum frequency is
25 MHz, typically run at 10 MHz. In normal
operation this pin should be pulled either
high or low. Recommend external pull-down.
JTAG test mode select. Synchronous to
JTAG_TCK rising edge. Used by the Test
Access Port controller to set certain test
modes.
JTAG test data input. Synchronous to
JTAG_TCK.
JTAG test data output. Synchronous to
JTAG_TCK.
