IT0/IT1=> Used for timer Interrupts when IT0/IT1=1 specifies interrupt on delays in it. since 8051 is an 8-bit micro controller, we access its register in two bytes one byte The major purpose of B(Extension register) register is executing multiplication single instruction for multiplication (MUL) and division (DIV). SP (STACK 5 Jan 2012 8051 micro controller special function registers like Accumulator (Acc), DPTR of 8051, Register B, PSW register, PCON register, Port registers. The 8051 micro controller has a single instruction for multiplication (MUL) and 20 Dec 2016 8051 Timer Control (TCON) Special Function Register. Bit, Symbol, TCON Bit Function. 7, TF1l, Timer 1 Overflow flag. Set when timer rolls from all 1's to 0. 18 Mar 2017 8051 timer how to use its timers, types of timers and mode and control Now stop the timer with the instructions “CLR TR0” for timer0 or “CLR TR1” for timer1. Bits, symbols and functions of every bits of TCON register are as30 Nov 2017 A tutorial on 8051 Microcontroller Special Function Registers or SFRs. In the previous 8051 Microcontroller Tutorial, we have seen the Instruction Set . Timer Control or TCON Register is used to start or stop the Timers of 27 Oct 2014 The 8051 has two counters/timers which can be used either as timer to In this TMOD register, lower 4 bits are set aside for timer0 and the It is done by the instruction “SETB TR0” for timer 0 and “SETB TR1” for timer1. TCON register- Bits and symbol and functions of every bits of TCON are as follows:. Mode selection Values of timers and counter in 8051. Timer Control Register (TCON): TCON is another register used to control operations of counter and timers in microcontrollers. It is an 8-bit register wherein four upper bits are responsible for timers and counters and lower bits are responsible for interrupts. In the first section of this appendix, we describe the instructions of the 8051 and give their formats with some Function: Transfers control unconditionally to a new address. . Note: This flag does not latch low-level triggered interrupts.
