Subroutine call
Unconditionally calls a subroutine at the specified address. The Program Counter then
increments by 1 to obtain the address of the next instruction which is then pushed onto
the stack. The specified address is then loaded and the program continues execution
from this new address. As this instruction requires an additional operation, it is a two cy-
cle instruction.

Pre-clear Watchdog Timer
The TO, PDF flags and the WDT are all cleared. Note that this instruction works in con-
junction with CLR WDT2 and must be executed alternately with CLR WDT2 to have ef-
fect. Repetitively executing this instruction without alternately executing CLR WDT2
will have no effect.
