CLR WDT2 Pre-c�ear Watchdog Timer
SWAP [m] Swap nibb�es of Data Memor�
SWAPA [m] Swap nibb�es of Data Memor� with res��t in ACC
HALT Enter power down mode
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 "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 are consecutively executed. Otherwise the TO and PDF flags remain unchanged.
