What Is The Function Of CLK OUT Pin Of 8085?

by | Last updated on January 24, 2024

, , , ,

There are 3 clock signals, i.e. X1, X2, CLK OUT. X1, X2 − A crystal (RC, LC N/W) is connected at these two pins and is used to set frequency of the internal clock generator . This frequency is internally divided by 2. CLK OUT − This signal is used as the system clock for devices connected with the microprocessor.

What is the function of CLK?

Spliceosome factors target tim mRNA to control clock protein accumulation and circadian behavior in Drosophila. these results demonstrate a key role of Clk post-transcriptional control in stabilizing circadian transcription .

What is the function of intr pin in 8085 microprocessor?

INTR – It is an interrupt request signal . INTA’ – It is an interrupt acknowledgement sent by the microprocessor after INTR is received.

What is the function of the pin intr?

This is an interrupt signal, and the priority of this among the interrupts is low. This signal can be allowed or not allowed by the software. When INTR pin goes high then the 8085 microprocessor completes the instruction of current which is being executed and then recognizes the INTR signal and progresses it .

What is the function of ready and intr pin?

A17/S4 A16/S3 Function 1 1 Data segment access

What is the function of CLK OUT pin?

CLK OUT − This signal is used as the system clock for devices connected with the microprocessor .

What is CLK pin?

The CLK or clock pin, is used to clock data out of the data pin . One cycle of the clock pin puts another bit of the data out to the DATA pin. You gather these bits into a byte. You can do this “by hand” or use the SPI hardware inside the arduino chip.

What is purpose of Sid and sod?

Ans: SID (Serial input data line): It is an input line through which the microprocessor accepts serial data . SOD (Serial output data line): It is an output line through which the microprocessor sends output serial data.

What are the 2 modes of 8086?

8086 is designed to operate in two modes, i.e., Minimum and Maximum mode .

What is interrupt and its types?


Maskable Interrupt : The hardware interrupts which can be delayed when a much highest priority interrupt has occurred to the processor. Non Maskable Interrupt: The hardware which cannot be delayed and should process by the processor immediately.

What happens when a high is applied to reset pin?

When it is high, it indicates that the device is ready to transfer data . When it is low, it indicates wait state. It is available at pin 21 and is used to restart the execution. It causes the processor to immediately terminate its present activity.

Which Interrupt has the highest priority?

Interrupt Priority Mask TRAP (RST 4.5) 1 (Highest) Non-maskable RST 7.5 2 Maskable RST 6.5 3 Maskable RST 5.5 4 Maskable

What is type1 interrupt?

TYPE 1 interrupt represents single-step execution during the debugging of a program . TYPE 2 interrupt represents non-maskable NMI interrupt. TYPE 3 interrupt represents break-point interrupt. TYPE 4 interrupt represents overflow interrupt.

What are the pin operations in minimum mode?

In a minimum mode 8086 system, the microprocessor 8086 is operated in minimum mode by strapping its MN/MX pin to logic 1 . In this mode, all the control signals are given out by the microprocessor chip itself.

What is used to connect more microprocessor?

An address bus consists of the lines that connect between the microprocessor address pins and the address pins of each of the memory chips in the microprocessor system. In anything but a very simple system, the address bus would connect to other units also, but for the moment we will ignore these other connections.

Which stack is used in 8085?

Answer: LIFO (Last In First Out) stack is used in 8085.In this type of Stack the last stored information can be retrieved first.
