Address Bus (A[13:0]). This bus selects specific

registers during TECT3 register accesses.

Signal A[13] selects between normal mode and test

mode register access. A[13] has an integral pull down

resistor.

RSTB

Input

A22 Active Low Reset (RSTB). This signal provides an

asynchronous TECT3 reset. RSTB is a Schmitt

triggered input with an integral pull up resistor.

ALE

Input

D17 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

Test Clock (TCK). This signal provides timing for test

operations that can be carried out using the IEEE

P1149.1 test access port.
