4.3Firmware and System Design Information

4.3.1Board level pull-ups and pull-downs

Many of the HDMP-3001 input and tristateable outputs have internal pull-ups. Refer to the pin descrip- tion for detailed information on where external pull-ups are re- quired.

Table 16. Pin Connections – MPC860

4.3.2Motorola MPC860 Microprocessor Interface

The recommended setup of the interface is:

HDMP-3001 mapped to the smallest memory bank, 32 Kbytes.

BR[20-31] = 010000000001, which sets no parity, 8 bits data, GPCM controlled.

OR[20-31] = 000100001000, which sets normal CS timing, no burst allowed, externally generated TA.

Pin connections are described in Table 16.
