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.
