Mnemonic
1. For skip instructions, if the result of the comparison involves a skip then two cycles are required,
2. Any instruction which changes the contents of the PCL will also require 2 cycles for execution.
3. For the CLR WDT1 and CLR WDT2 instructions the TO and PDF flags may be affected by the
execution status. The TO and PDF flags are cleared after both CLR WDT1 and CLR WDT2 instructions
if no skip takes place only one cycle is required.
are consecutively executed. Otherwise the TO and PDF flags remain unchanged.
