66 / 267 page ![]() PRELIMINARY PM5366 TEMAP-84 DATASHEET PMC-2010672 ISSUE 1 HIGH DENSITY 84/63 CHANNEL VT/TU MAPPER AND M13 MULTIPLEXER PROPRIETARY AND CONFIDENTIAL 54 Pin Name Type Pin No. Function A[0] A[1] A[2] A[3] A[4] A[5] A[6] A[7] A[8] A[9] A[10] A[11] A[12] Input AB22 AA21 Y19 AA20 AA19 AB20 AA18 W19 AB18 AA17 W18 Y16 AA16 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 B1 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 D2 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 E3 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. |
