hello, thanks for the video. It would be nice if you covered a video on the working of the ALE and how address and data buses are multiplexed for external memory access. Thanks once again.
very nicely explained i was very confused as this is not provided in books and please i request you to upload for other microcontroller concepts thank u
When Port 0 is as input both FETs are open(0) and point is at high impedance=>pull up resistor does not activate When Port 0 is as output for 1 both FETs are open(0) and point is at high impedance => pull up resistor activates. Both are same conditions which means when in input mode it should always input Vcc. There's something wrong.
at 2.53 you say that the external device can write a 1 value to pin at high impedance state.Is that so..shouldn't it be connected to external pull up resistors.
If you want me to cover any related topics, kindly let me know. I am happy to help and will upload the video at the earliest. Thanks and Regards, EnggClasses
can anyone tell me for using the port 0 of the microcontroller of 89s52 as the out put port we have to use the pull up resistors what should be the value of those resistors
sir I have doubt when port 0 use as output port. When we want to send 0 , the lower FET in ON. At that time the pull up resister get ground so that at mid point we get 5V instead of 0. So i am confuse at that point.
underrated video!!Such gems get unnoticed.
Really best video ever
very nice explanation in simple words i read 2 books but here explanation is very much up to the mark nice work
Very good and clear explanation👍. It cleared all my doubts
Thanks for the comment
U sir cleared a lot of doubts .hats off 🔥
Thanks for the comment, you may also like a video on

Sir why didn't we add pullup resistor in case of port 0 as input when it has high impedance state
Save me before my Embedded System exam! Thank you 谢谢!
Thank you professor! It was really helpful.
+Prince Rachit , Thank you Prince Rachit.!
Good explanation 👍👍
Thank you so much sir...!! actually it was a bit tricky topic but u made me understand it so easily...!
very nicely explain and too helpful...keep uploading👏👏👏
Nice work, really well explained.
nyc explanation sir..understood the concept finally of port 0 :)
very nicely explained i was very confused as this is not provided in books and please i request you to upload for other microcontroller concepts thank u
+shashank shanbhag, Thank you so much Shashank, thanks for the appreciation.!
I like this video...pls explain all other ports ....like this
it was awesome.. bro!
keep uploading videos.. u teach very well
Good !! Can you upload video on the Timers and the operating modes of timers of 8051 ?
thank you sir, for brief explanation .i never seen in any books such explanation that you will do.
noor basha Thanks for the comment and stay subscribed for more videos on 8051.
What kind of software and stylus pen your using kindly send me. How you make this videos.
Good explanation 🙏🙏
bhai mast exaplaination diya hai
When Port 0 is as input both FETs are open(0) and point is at high impedance=>pull up resistor does not activate
When Port 0 is as output for 1 both FETs are open(0) and point is at high impedance => pull up resistor activates.
Both are same conditions which means when in input mode it should always input Vcc.
There's something wrong.
Excellent explaination.Thanks Sir,Can you please upload a tutorial on I2C Protocol
Great explanation keep it up👍
Thanks Sir
very nyc explanation sir ..helped me alot
A video on Port 1 of 8051 is added, kindly find the link below. Subscribe to channel for more videos on 8051.

Great Job Sir
Do keep up ur good Wrk
Lucid explanation!!!
at 2.53 you say that the external device can write a 1 value to pin at high impedance state.Is that so..shouldn't it be connected to external pull up resistors.
External pull-ups are for bringing 0 to 1 , in your case , you're already supplying 1 from an external device , hence no need for a pull-up resistor.
@@PriyanshGupta2906 thanks
if I want to acces P0 is it right to do it like this ? P0 = 0x80, P1 = 0x90, P2 = 0xA0 and P4 = 0xB0 ?
Perfect explanations
pls, upload full video of i2c protocol...
Thanks a lot sir, nice explanation
If you want me to cover any related topics, kindly let me know. I am happy to help and will upload the video at the earliest.

Hi sir,
With the same port 0 diagram, one buffer is connected at read pin, read latch, what is the significance of the buffer?
Embedded system topic sir
thank u so much
can anyone tell me for using the port 0 of the microcontroller of 89s52 as the out put port we have to use the pull up resistors what should be the value of those resistors

Thanks
amazing sir ..thank u sooo much .
thank you so much sir
+Swapnil Karane, Thank you Swapnil.!
Thanks mehn helped a lot
"port 0 as input" u giving 1 at D its ok, but "port 0 as output" u giving 1 at D which acts as input, then how can it act as output??????
thanks a lot sir
+Joshua kar, Thank you Joshua.!
thank you
