#65079 - RE: 8051/8255 interfacing
Responding to: ???'s previous message
Hi,
i found the output voltage at some of the pins to be 2.8 volts

it is average voltage due MCU works. For example, it may be found at ALE pin, at pins WR/RD/P0/P2 during MCU executes MOVX@ to external data memory.

Regards,
Oleg
