B. If the internal RAM of the 8051 in increased to 512 B instead of 256 B, where half of the RAM is used for GPR and the other half is used for SFR. Furthermore, in the GPR the address from 30 H to 4F H is used as the bit addressable area, Find: 1. The address range of the bytes in the BIT ADDRESSABLE AREA. 2. The address range of the bits in the BIT ADDRESSABLE AREA. 3. What is the address of bit number 87 H? 4. Given the Byte 39 H, what is the address of the bit at location 2? (Note, we always start at location ) 5. How many bytes are there in the BIT ADDRESSABLE AREA? 6. How many bits are in the BIT ADDRESSABLE AREA?
