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

Note:
p is 0 to 15 for M34501M2 and p is 0 to 31
for M34501M4/E4.

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 M34501M2 and p is 0 to 31
for M34501M4/E4.
Be careful not to over the stack because the
maximum level of subroutine nesting is 8.
