What is the function of CLK OUT pin of 8085?
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.
Why does a microprocessor need clock pin?
The clock input provides the basic timing for processing operation and bus control activity. Its an asymmetric square wave with a 33% duty cycle. RESET : This pin requires the microprocessor to terminate its present activity immediately.
Which pin number is for reset out in 8085?
RESET IN – It is pin number 36 in the pin diagram. An active low signal at this pin resets the PC of the microprocessor to 0. Or we can say, after resetting the PC holds its initial memory address. RESET OUT – It is the 3rd pin in the pin diagram.
What is a system trap?
In computing and operating systems, a trap, also known as an exception or a fault, is typically a type of synchronous interrupt caused by an exceptional condition (e.g., breakpoint, division by zero, invalid memory access).
Is a system call a trap?
System calls are accomplished by moving parameters to registers and then calling int 2e to trap into the kernel. Exceptions and interrupts, whether arising from external events, internal faults, or software generated using the int instruction, are vectored throught Interrupt Descriptor Table, the IDT.
What is pinout cables?
Pinout or pin-out is a term used in electronics to describe how an electrical cable is wired, or the function of each wire (pin) in a connector. An electrical connector typically consists of several electrical contacts or pins that can be used to carry electrical power or signals.
What’s the difference between RJ11 and Rj12?
The difference between Rj11 and Rj12 is that Rj11 is a connection jack that creates a bridged connection for single telephone line which uses flat stain cable for household wire telephone and modem connections, while Rj12 is a connection jack that enjoins central telephone system with single telephone lines through a …
How many types of cable pins are there?
There are different types of cables in the market, like HDMI cable, VGA cable, DVI cable, Ethernet cable, PS/2 cable, 3.5 mm audio cable, USB cable, and computer power cord cable.
How do you count connector pins?
Column count is simply starting at the bottom of the row on the right (female) on the left (male) and count up to the top. You then pick up the count at the bottom of the next row to the left/right and count to the top again.
How do you wire a 3 wire plug with 2 wires?
An appliance with only two wires will be double- insulated not requiring an earth wire. Connect the two wires to the live and neutral prongs of the 3-prong plug. If the wires are color-coded, make sure to connect live to live terminal and neutral to the neutral terminal.
Can I put a 3 pin plug on a 2 pin?
Yes, it is safe to replace a 2-pin plug with a 3-pin plug, but be completely aware that the ground pin does no good at all unless there happened to be a third ground conductor in the original (or replacement) cord and you connected it appropriately.
What wires are in a 2 pin plug?
There is no earth wire in a two-pin plug. If the wires are colored, the white one is supposed to be the neutral and the black one is supposed to be hot. With zipcord, the side with ridges is supposed to be neutral.
