65 / 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 53 Pin Name Type Pin No. Function Microprocessor Interface INTB Output OD T21 Active low Open-Drain Interrupt (INTB). This signal goes low when an unmasked interrupt event is detected on any of the internal interrupt sources. Note that INTB will remain low until all active, unmasked interrupt sources are acknowledged at their source. CSB Input AA15 Active Low Chip Select (CSB). This signal is low during TEMAP-84 register accesses. The CSB input has an integral pull up resistor. RDB Input W17 Active Low Read Enable (RDB). This signal is low during TEMAP-84 register read accesses. The TEMAP-84 drives the D[7:0] bus with the contents of the addressed register while RDB and CSB are low. WRB Input AB16 Active Low Write Strobe (WRB). This signal is low during a TEMAP-84 register write access. The D[7:0] bus contents are clocked into the addressed register on the rising WRB edge while CSB is low. D[0] D[1] D[2] D[3] D[4] D[5] D[6] D[7] I/O U22 T20 V19 U21 U20 W22 Y22 Y21 Bidirectional Data Bus (D[7:0]). This bus provides TEMAP-84 register read and write accesses. |
