Address Bus (A[13:0]). This bus selects specific
registers during TECT3 register accesses.
D18
Signal A[13] selects between normal mode and test
mode register access. A[13] has an integral pull down
resistor.

RSTB
Input A22
Input D17
Active Low Reset (RSTB). This signal provides an
asynchronous TECT3 reset. RSTB is a Schmitt
triggered input with an integral pull up resistor.
Address Latch Enable (ALE). This signal is active
high and latches the address bus A[13:0] when low.
When ALE is high, the internal address latches are
transparent. It allows the TECT3 to interface to a
multiplexed address/data bus. The ALE input has an
integral pull up resistor.

JTAG Interface
TCK
Input C3
Test Clock (TCK). This signal provides timing for test
operations that can be carried out using the IEEE
P1149.1 test access port.
