How many registers register in TCON?
How many registers register in TCON?
They are 16-bit registers. we give our time delays in it. since 8051 is an 8-bit micro controller, we access its register in two bytes one byte for TH(timer high byte) and one for TL(timer low byte).
What is TMOD in 8051?
8051 has a Timer Mode Register and Timer Control Register for selecting a mode of operation and controlling purpose. TMOD is an 8-bit register used to set timer mode of timer0 and timer1. Bit 7,3 – GATE: 1 = Enable Timer/Counter only when the INT0/INT1 pin is high and TR0/TR1 is set.
What is TCON register?
TCON (Timer Control) Timer Control or TCON Register is used to start or stop the Timers of 8051 Microcontroller. It also contains bits to indicate if the Timers has overflowed. The TCON SFR also consists of Interrupt related bits.
What is the role of the TMOD register in microcontroller?
The TMOD register is used to select the operating mode and the timer/counter operation of the timers. The format of TMOD register is, The lower four bits of TMOD register is used to control timer-0 and the upper four bits are used to control timer-1.
What is TMOD and TCON?
Counters and Timers in 8051 microcontroller contain two special function registers: TMOD (Timer Mode Register) and TCON (Timer Control Register), which are used for activating and configuring timers and counters.
How many registers are there in 8051?
The 8051 has 4 selectable banks of 8 addressable 8-bit registers, R0 to R7. This means that there are essentially 32 available general purpose registers, although only 8 (one bank) can be directly accessed at a time.
What is the length of TCON register 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.
What is the function of TMOD register Mcq?
TMOD register is used to set different timer’s or counter’s to their appropriate modes so that it tells the user that what mode is being used when operating any timer or counter.
What is the full form of TCON?
TCON. Timer/Counter Control Register (Intel 8051 Microcontroller register)
