Address Bus (A[12:0]). This bus selects specific

registers during TEMAP-84 register accesses.

Signal A[12] selects between normal mode and test

mode register access. A[12] has an integral pull down

resistor. Tie A[12] directly to ground unless access to

bit HIZIO in test register 0x1000 is required.

RSTB

Input

W20 Active Low Reset (RSTB). This signal provides an

asynchronous TEMAP-84 reset. RSTB is a Schmitt

triggered input with an integral pull up resistor.

ALE

Input

AA22 Address Latch Enable (ALE). This signal is active

high and latches the address bus A[12:0] when low.

When ALE is high, the internal address latches are

transparent. It allows the TEMAP-84 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.

TMS

Input

Test Mode Select (TMS). This signal controls the test

operations that can be carried out using the IEEE

P1149.1 test access port. TMS is sampled on the

rising edge of TCK. TMS has an integral pull up

resistor.

TDI

Input

Test Data Input (TDI). This signal carries test data into

the TEMAP-84 via the IEEE P1149.1 test access port.

TDI is sampled on the rising edge of TCK. TDI has an

integral pull up resistor.
