BS2 is a interpreter chip, Could anyone tell me the exection time of each BS2
instruction ?

Fox example: Low 1 ' low pin1
High 2 ' high pin 2

How much total time of above two BS2 instructions ? ( according to the
manual, each instruction
need 0.3 msec , therefore above two BS2 instruction need 0.6 msec, Is it true ?
) IF
it's true, I need to change my application circuit.

Thank u in advance

Baker

    Dear Baker,

    Those commands take only 140 microseconds. The actual interpretation times
    for different commands vary widely. I have a short list posted at:

    I am also interested in the execution times for the Lookup and
    Shiftout and Shift in as used in A/D conversion. Have problems assassing the
    site listed below.
