Note:
1. For skip instructions, if the result of the comparison involves a skip then two 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 ²CLR WDT1² and ²CLR WDT2² instructions the TO and PDF flags may be affected by the
execution status. The TO and PDF flags are cleared after both ²CLR WDT1² and ²CLR WDT2² instructions
are consecutively executed. Otherwise the TO and PDF flags remain unchanged.
