machine cycles long. However in the W77LE532, the user has a facility to stretch the duration of this
instruction from 2 machine cycles to 9 machine cycles. The
RD
and
WR
strobe lines are also
proportionately elongated. This gives the user flexibility in accessing both fast and slow peripherals
without the use of external circuitry and with minimum software overhead. The rest of the instructions
are either three, four or five machine cycle instructions. Note that in the W77LE532, based on the
number of machine cycles, there are five different types, while in the standard 8032 there are only
three. However, in the W77LE532 each machine cycle is made of only 4 clock periods compared to
the 12 clock periods for the standard 8032. Therefore, even though the number of categories has
increased, each instruction is at least 1.5 to 3 times faster than the standard 8032 in terms of clock
periods.
