Ma'am what would be the C upper and lower signal in Mode1 (if Pc is handshaking) ?
@TechnoTutorials2783
@TechnoTutorials2783 Год назад
Both will be used FOR handshakes 🤝 means one port sen request another will send acknowledgement for request
@VishalAryavart
@VishalAryavart Год назад
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 🙏🏻

@TechnoTutorials2783
@TechnoTutorials2783 Год назад
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

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
