Counter Latch Clock. The clock present at this input can be divided internally
to produce the latch signal for the internal counters. Refer to the Counter
Transfer Command register for more details. This pin has an internal
pull-down.
System Reset. This is an active low input signal. It causes the device to enter
the initial state. The Clk signal must be active to reset the internal registers.
JTAG Test Clock. TCK should be pulled down if not used.
JTAG Test Mode Select. TMS is sampled on the rising edge of TCK.
JTAG Test Data Input. This pin has an internal weak pull-down.
JTAG Test Reset (active low). Should be asserted LOW on power-up and
during reset. Must be HIGH for JTAG boundary-scan operation. This pin has
an internal weak pull-down.
Test1. Must be tied Low
Test3. Must be pulled up to V3.3 for normal operation. NOT 5V TOLERANT.
signals, otherwise, connect to a 3.3 Volt supply.
