9.8 Subroutine Instructions
The program memory consists of pages in steps of 1K (000H to 3FFH). However, as the assembler automatically
performs page optimization, it is unnecessary to designate pages. The pages allowed for each product are as
follows.

addr
<2> Cycle count
<3> Function
Increments (+1) the stack pointer value and saves the program counter value in the address stack
register. Then, enters the address specified with the operand addr (a
9
to a
0
) into the program counter.
If a carry is generated when the stack pointer value is incremented (+1), an internal reset takes effect.

SP – 1
Restores the value saved in the address stack register to the program counter. Then, decrements
(–1) the stack pointer.
If a borrow is generated when the stack pointer value is decremented (–1), an internal reset takes effect.
