All registers in Microcontroller 8051 are called as Special Function Registers(SFR). They are:
1)Register-A(Accumulator)-bit and byte addressable
2)Register-B-bit and byte addressable
3)Program Status Word(PSW)-bit and byte addressable
4)Stack Pointer(SP)
5)Low Byte DPTR(DPL)
6)High Byte DPTR(DPH)
7)Port 0(P0)-bit and byte addressable
8)Port 1(P1)-bit and byte addressable
9)Port 2(P2)-bit and byte addressable
10)Port 3(P3)-bit and byte addressable
11)Interrupt Priority Control(IP)-bit and byte addressable
12)Interrupt Enable Control(IE)-bit and byte addressable
13)Timer/Counter Mode Control(TMOD)
14)Timer/Counter Control(TCON)-bit and byte addressable
15)Timer/Counter 0 High Byte(TH0)
16)Timer/Counter 0 Low Byte(TL0)
17)Timer/Counter 1 High Byte(TH1)
18)Timer/Counter 1 Low Byte(TL1)
19)Serial Control(SCON)-bit and byte addressable
20)Serial Data Buffer(SBUF)
21)Power Control(PCON)
Accumulator (A), B-Register, Stack Pointer (SP), Program counter (PC) , Instruction register
control register are present in 8051:
TCON, TMOD, SCON, PCON, IP, & IE.
