What is ALE? Explain the functions of ALE in 8085.
Answer Posted / dhanashree arun ghadage
1) address latch enable, one special output signal generated by microprocessor to indicate begining of operation.
2) it is positive going pulse generated during 1st clock cycle of machine state & it's indicate that the bits on AD7-AD0 are address bits.
3) this signals enable to lower 8-bit of the address from the multiplexed bus to latch into external flip- flop or peripheral devices .after AD0-AD7 changes over to data bus .
4) ale is never tristated.
