Your embedded system has an 8-bit microprocessor, which has a 16-bit address bus. In addition, you have a 32-Kbyte Flash chip, a 16-Kbyte SRAM chip, and a 16 KByte DPRAM chip. You want to locate the FLASH chip right in the beginning of the address space, the SRAM chip just after it, and the DPRAM at the end of the address space. All the memory chips have a single /CS selection line, which is controlled by a fast 8 x 4 OTP-ROM chip.
What are you going to program into the contents of the OTP-ROM, and how do you connect it to the microprocessor and the memory chips?
