Fill in the blanks to submit your answer to the following questions: (a) The lowest memory address associated with the 512KB RAM is .Write the complete 20-bit address in HEXADECIMAL notation without spaces. Note: For example, the lowest memory address associated with the RESERVED region is 0x00000 in HEXADECIMAL notation. (b) The highest memory address associated with the 512KB RAM is .Write the complete 20-bit address in HEXADECIMAL notation without (c) The memory-mapped 10 address of the 1B Keyboard register is .Write the complete 20-bit address in HEXADECIMAL notation without (d) Say we utilize a DMUXBWay to route the load signal to the various regions of the memory in order to perform a data write. What would be the binary values of the DMUXBWay select bits needed in order to perform data write to SCREEN? Note: For example, if the select bits 2:0 were 011 then you'd write Ob011 or 011
