Connect MP address lines A9-A0 to PROM's A9-A0 pins But what do we do with MP's A11 and A10 address lines? Connect by the below ==> each PROM chip will be selected upon the state (1 or 0) of MP's A11 and A10 lines So addresses 00 00 0000 0000 - 00 11 1111 1111 (0x000-0x3FF) 01 00 0000 0000 - 01 11 1111 1111 (0x400-0x7FF) 10 00 0000 0000 - 10 11 1111 1111 (0x800-0xBFF) 11 00 0000 0000 - 11 11 1111 1111 (0xC00-0xFFF) Three inputs NAND chip and scheme Scheme used four of the PROM chips and four three-input NAND gates (CS = chip select pins) Scheme to coonect 12 input pins MP address to four PROM 10 address pins == MEMR (Merory Read) 11. You are designing a multi-user interface that stores user preference data on external memory. You decided to use a PIC18F45K20 microcontroller and 24C02C EEPROM memory
