CALL addr Subroutine call
Description 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.
