How is 8255 (Programmable Peripheral Interface) configured if its control register contains 9B h.
Ans.
Programmable Peripheral Interface
Command Byte B (sets or resets any bits in port C)
BH => 1001 1011 =>
6b5=00-> Mode0
4=0-> Port A as input
3=1-> Port C as input (PC7-PC4)
2=0-> Mode 0
1=1-> Port B as input
0=1-> Port C as input (PC3-PC0).
A circuit realization of a NAND gate will now be developed. By connecting NAND gates together in various ways, one can synthesize other gates and flip-flops. Thus in principle, a s
