A memory map for a system with a 16-bit address bus is initially planned as: 0xC000-0xFFFF Region 1
0xA000-0xBFFF unused
0x8000-0x9FFF Region 2
0x4000-0x7FFF unused
0x0000-0x3FFF Region 3
The unused addresses surrounding Region 2 potentially offer an opportunity to use lazy address decoding to simplify the logic for Region 2. If address bit 13 is treated as a "don't care," what would be the new address range for Region 2?
0x7000-0x9FFF
0x6000-0x9FFF
0x8000-0xBFFF
0xC8000-0xAFFF
