Subroutine call
Unconditionally calls a subroutine at the specified address. The Program Counter then in-
crements 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 cycle instruc-
tion.

tion with CLR WDT2 and must be executed alternately with CLR WDT2 to have effect. Re-
petitively executing this instruction without alternately executing CLR WDT2 will have no
effect.
