A microprocessor is capable of addressing 1 megabyte of memory with a 20-bit address bus. The system to be designed requires 256 K bytes of RAM, 256 K bytes of EPROM, 16 I/O devices (memory mapped I/O) and 1 K byte of EERAM (electrically ... equivalent to two clock cycles for memory read and write. Assuming control signals similar to 8085, design the extra logic required for interfacing EERAM.
Choose the correct alternatives (more than one may be correct) and write the corresponding letters only: The TRAP interrupts mechanism of the $8085$ microprocessor: (a). executes an $RST$ by hardware (b). executes an instruction supplied by an external device through the $INTA$ signal (c). executes an instruction from memory location $20H$ (d). executes a NOP (e). none of the above
