Explanation:
Detailed explanation-1: -In all members of the 8051 family, the first 32 bytes of DATA memory (0x00-0x1F) is grouped into 4 banks of 8 registers each. Programs access these registers as R0-R7. The register bank is selected by two bits of the program status word, PSW.
Detailed explanation-2: -The 8051 architecture supports a 64KB linear pro-gram memory space. Devices that have more than 64KB of program memory implement a code bank-ing scheme to surmount this 64KB limit.
