Answer Posted / mrinmoy karan
Program Counter (PC) and Stack Pointer (SP) are basically
used to hold 16-bit memory addresses.PC stores the 16-bit
memory address of the next instruction to be fetched.SP can
be used to temporarily store the 16-bit memory address as
well as data.So PC & SP are 16-bit registers.
