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 JFET for which V A = 80 V, V P = 4 V, and I DSS = 10 mA has a quiescent drain current of 3 mA when used as a common-source amplifier for which R D = R SS = 1k and R L = 3k
Q. Show Advantages of Oscillators? Although oscillations can be produced by mechanical devices (e.g. alternators), but electronic oscillators have the following advantages:
