What else can I help you with?
How many instruction in 8051 microcontroller?
how many interrupts in 8051
Why reset circuit needed in 8051?
You need a reset circuit in the 8051, as in every logic circuit, in order to ensure that it starts up in a known state.
Name of instruction to reset the interrupt?
software interrupts
In the 8051 what value does the stack pointer contain immediately after reset?
07H
Why 8051 microcontroller called so?
Because it is 8- 8-bit controller (8000 series) 5- It has 5 interrupts 1- It has only one serial communication port
Who is first invented 8051 microcontroller or 8051 microprocessor?
Intel
Why the name 8051 as 8051?
because i said so thats why
What are the various type of interrupts?
There are three types of interrupts.... 1. internal Interrupts 2. External Interrupts 3. Software Interrupts... read more
What is the difference between microcontroller 8051 and avr atmega16?
avr is high speed cmpar to 8051.in 8051 there are less number of instructions
How many interrupts in?
it has 256 interrupts ..
How much voltage is required to energize the 8051 microcontroller?
The 8051 runs on +5vdc.
Why there is a need for disabling interrupts in 8085?
Interrupt are automatically disabled on interrupt entry (except for TRAP, which is non-maskable) so that interrupts do not, by default, nest. You would also disable enterrupts surrounding a critical section of code that, perhaps, manipulated an interrupt register. It is possible to re-enable interrupts during an interrupt service routine. Typically, you would have a hierarchy, such as RST7.5, then RST 6.5, then RST 5.5. Initially, at interrupt entry, all interrupts are disabled. You could then manipulate the interrupt mask using the RIM and SIM instructions and enable further interrupts, allowing a nested architecture. At interrupt exit, then, you would disable interrupts, reset the mask, enable interrupts, and return from interrupt.
