12.5 Intel & Motorola Microprocessor Direct Access
The KS9245 is designed to be directly interfaced with Intel and Motorola type microprocessors
without any external glue logic (refer to the Microprocessor Interface timing in section 9.1.1 and
9.1.2). The following diagrams show the connections for an Intel-type and Motorola-type
microprocessor connected to the KS9245 in a direct access configuration.
Note: ISEL and MSEL
can still used as BADD7 and BADD8 to connect to DRAM addresses.
