Grouping:
Subroutine call operation
Description: Call the subroutine in page 2 : Calls the
subroutine at address a in page 2.
Note:
Subroutine extending from page 2 to an-
other page can also be called with the BM
instruction when it starts on page 2.
Be careful not to over the stack because the
maximum level of subroutine nesting is 8.
