How many registers in 8051
WebTCON Register: In addition to the above two registers, the TCON register specifies the type of external interrupt to the 8051 microcontroller, as shown in the figure. The two external interrupts, whether edge or level triggered, specify by this register by a set, or cleared by appropriate bits in it. And, it is also a bit addressable register. WebIntel Corporation is the first company who presented 8051 microcontroller in the market. It is an 8-bit microcontroller. It has on-chip 128 bytes of RAM, 4K bytes ROM, two timers, one serial port, and four general-purpose input/output ports. Each port has an 8-bit register.

The other is TCON. TMOD (Timer mode register) – The timer registers can operate in four different modes. We’ll take a look at all these modes in a jiffy.
Web8 okt. 2024 · The 8051 contains two 16-bit registers: the program counter (PC) and the data pointer (DPTR). Each is used to hold the address of a byte in memory. Program instruction bytes are fetched from locations in memory that are addressed by the PC. What is TCON register? TCON (Timer Control register) TCON is an 8-bit register. Web28 apr. 2024 · 1 Answer. You can't, at least address the register's name directly in an instruction. That's because 8051 instructions were designed to be encoded with a single byte, or a byte plus an immediate. That byte contains the opcode and 3 bits for the register number. Thus you can only encode 8 registers in the instruction.
Web8051 and to 256 bytes in 8052, internal memory pointers are 8 bits in size. The stack in 8051 family must reside in the internal memory. The stack pointer is therefore an 8 bit register. This is a special function register located at address 81H. The stack grows upwards using pre-increment and post decrement for the stack pointer.
