underrated video!!Such gems get unnoticed.

[@HariSingh-fi1sd]

very nice explanation in simple words i read 2 books but here explanation is very much up to the mark nice work

[@reformedyouth350]

Thank you so much sir...!! actually it was a bit tricky topic but u made me understand it so easily...!

[@EnggClasses]

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

Hi sir, With the same port 0 diagram, one buffer is connected at read pin, read latch, what is the significance of the buffer?

[@ejazalam7655]

Embedded system topic sir

[@sunnygangwal6749]

it was awesome.. bro! keep uploading videos.. u teach very well

[@Sachindeo93]

Nice work, really well explained.

Great Job Sir Do keep up ur good Wrk

[@l3av3m3al0n]

Thanks mehn helped a lot

[@stvarsoul]

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.

[@rohitkunta8328]

Good explanation 👍👍

[@rahulmahbubani1392]

bhai mast exaplaination diya hai

[@vinjamurisaideepika7792]

Sir why didn't we add pullup resistor in case of port 0 as input when it has high impedance state

[@soniyabenny8341]

Good explanation 🙏🙏

[@gauravjagdale3949]

Good !! Can you upload video on the Timers and the operating modes of timers of 8051 ?

[@neelu1921]

thank u so much

[@RealEyes24]

if I want to acces P0 is it right to do it like this ? P0 = 0x80, P1 = 0x90, P2 = 0xA0 and P4 = 0xB0 ?

[@joshuapinto7]

thanks a lot sir

[@EnggClasses]

+Joshua kar, Thank you Joshua.!

[@shashankshanbhag8529]

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

[@EnggClasses]

+shashank shanbhag, Thank you so much Shashank, thanks for the appreciation.!

[@jayamreliya0804]

pls, upload full video of i2c protocol...

[@SandeepGurram810]

thanks sir

[@vipulsoman]

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.

[@swethaabraham4321]

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.

[@PriyanshGupta2906]

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.

[@swethaabraham4321]

@@PriyanshGupta2906 thanks

[@lalitSharma-vh7jl]

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

[@riyakulkarni4142]

10k

[@lalitSharma-vh7jl]

Thanks

[@tailordhaval]

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.

[@kesavanram3657]

"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??????
