Embedded Software Development

Using specific programming languages (like C and C++) to write code for a specific hardware device in which it runs is called embedded software development. It makes the device smart by performing actions based on user's input which improves the user experience. They are designed to perform function-specific tasks rather than doing multiple tasks like computers. The embedded system is incredibly intuitive. An embedded software system could be a system developed and organized on any device, apart from an old-fashioned computer. It is the brain of a specific device; however, it is a solely useless tool and simple to elucidate what software system is embedded.

Question

A. Show the output waveform of the 8254 interval timer when the following code is executed.
(Assume: the 8254 ports are 90H, 92H, 94H, and 96H. The input clock to the three counters
is 5.12 MHz.)-
MOV AL, 10110110B
OUT
96H, AL
MOV AL, 0OH
OUT
94H, AL
MOV AL, 02H
OUT
94H, AL

B. Choose the correct answer:
1) If we have one master interrupt controller connected with 2 slave interrupt controllers,
then the maximum number of devices (interrupt requests) that can be connected is:
22
24
26
16
64
2) If two salves are connected to a master 8259 PIC at IR3 and IR4 then the ICW3 of the
master should be
03H
зон
OCH
сон
None of these
3) in 8259, if automatic end of interrupt with rotating priority is required then the AEOI
should be set to 0 in ICW4
True
False
