A 1 Kbyte memory module has to be interfaced with an 8-bit microprocessor that has 16 address lines. The address lines A0 to A9 of the processor are connected to the corresponding address lines fo the memory module. The active low chip select \(\overline {CS}\) of the memory module is connected to the y5 output of a 3 to 8 decoder with active low outputs. S0, S1, and S2 are the input lines to the decoder, with S2 as the MSB. The decoder has one active low \({\overline {EN} _1}\) and one active high EN2 enable lines as shown below. The address range(s) that gets mapped onto this memory module is (are) |
| A. | 3000H to 33FFH and E000H to E3FFH |
| B. | 1400H to 17FFH |
| C. | 5300H to 53FFH and A300H to A3FFH |
| D. | 5800H to 5BFFH and D800H to DBFFH |
