Function
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.
asynchronous TEMAP-84 reset. RSTB is a Schmitt
triggered input with an integral pull up resistor.
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.
Test Clock (TCK). This signal provides timing for test
operations that can be carried out using the IEEE
P1149.1 test access port.
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.
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.
