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.
Operation:

Description: Call the subroutine : Calls the subroutine at
address a in page p.
Note:
p is 0 to 15 for M34502M2, and p is 0 to 31
for M34502M4/E4.
Be careful not to over the stack because the
maximum level of subroutine nesting is 8.

Grouping:
Subroutine call operation
Description: Call the subroutine : Calls the subroutine at
address (DR2 DR1 DR0 A3 A2 A1 A0)2 speci-
fied by registers D and A in page p.
Note:
p is 0 to 15 for M34502M2, and p is 0 to 31
for M34502M4/E4.
Be careful not to over the stack because the
maximum level of subroutine nesting is 8.
