10 INSTRUCTION
The W78E516D/W78E058D series execute all the instructions of the standard 8052 family. The
operations of these instructions, as well as their effects on flag and status bits, are exactly the same.
However, the timing of these instructions is different in two ways. Firstly, the machine cycle is 12 clock
periods, while the standard-8051/52 machine cycle is twelve clock periods. Secondly, it can fetch only
once per machine cycle (i.e., 12 clocks per fetch), while the standard 8051/52 can fetch twice per
machine cycle (i.e., 12 clocks per fetch).
