Note: 1. For skip instructions, if the result of the comparison involves a skip then up to three cycles are required, if
no skip takes place only one cycle is required.
2. Any instruction which changes the contents of the PCL will also require 2 cycles for execution.
3. For the “CLR WDT” instruction the TO and PDF flags may be affected by the execution status. The TO
and PDF flags are cleared after the “CLR WDT” instructions is executed. Otherwise the TO and PDF
flags remain unchanged.
