6.1.3 Instruction Set Summary
MiDAS1.1 Family
The MiDAS1.1 family has a special internal architecture and different timing to the standard 80C52.
This means the relative duration of the individual instructions, i.e. the number of clock cycles per
instructions, is different to that of 80C52.
Table 6-3 Summary of Instruction Set
Caution:
The instruction set of the MiDAS1.1 family is compatible with that of the well-known 80C52.
