Explanation:
Detailed explanation-1: -Answer: c) Accumulator is not a special function register.
Detailed explanation-2: -The Special Function Register (SFR) is the upper area of addressable memory, from address 0x80 to 0xFF. This area of memory can’t be used for data or program storage, but is instead a series of memory-mapped ports and registers.
Detailed explanation-3: -The 8051 family of microcontrollers provides a distinct memory area for accessing Special Function Registers (SFRs). SFRs are used in your program to control timers, counters, serial I/Os, port I/Os, and peripherals. SFRs reside from address 0x80 to 0xFF and can be accessed as bits, bytes, and words.
