Function
Bidirectional Data Bus (D[7:0]). This bus provides
TECT3 register read and write accesses.
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.
asynchronous TECT3 reset. RSTB is a Schmitt
triggered input with an integral pull up resistor.
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.
Test Clock (TCK). This signal provides timing for test
operations that can be carried out using the IEEE
P1149.1 test access port.
