[@VishalAryavart]

This video completes here, after the ma'ams explanation. Thanks for the questioning also thanks to ma'am for making such videos which is easier to grasp.

[@VishalAryavart]

Ma'am what would be the C upper and lower signal in Mode1 (if Pc is handshaking) ?

[@TechnoTutorials2783]

Both will be used FOR handshakes 🤝 means one port sen request another will send acknowledgement for request

[@VishalAryavart]

Thanks ma'am for your valuable response. As I understand PCl and PCu both will have high (1), in above described case.... Correct me if I'm wrong 🙏🏻

[@rahulmaurya6451]

mam,,, mode 2 select krne ke liye PORT A me kya Conditions rhengi ??

[@TechnoTutorials2783]

D7 =1 D6 and D5 10 or 11 D4 and D3 1/0 means as input/output Port D2 will 1/0 becoz group.B mode 2 mai kaam nahi karta D1=1/0 D0 =1/0

[@JOYSHJAYARONJOSEURKCS]

isn't D0 supposed to be BSR bit?

[@TechnoTutorials2783]

If D7 is 0 means BSR mode Let WE WANT TO RESET PC5 THEN D7=0 for bsr mode D3D2D1=101. FOR port PC5 and D0=0 for reset If u want to set then D0 =1
