POP <src>
Function:
Pop from stack.
Description:
Reads the contents of the on–chip RAM location addressed by the stack pointer, then decrements the stack pointer by
one. The value read at the original RAM location is transferred to the newly addressed location, which can be 8–bit
or 16–bit.
Example :
The stack pointer contains 32h and on–chip RAM locations 30h through 32h contain 01h, 23h, and 20h, respectively.
After executing the instruction sequence:
the stack pointer contains 30h and the data pointer contains 0123h. After executing the instruction POP SP the stack
pointer contains 20h. Note that in this special case the stack pointer was decremented to 2Fh before it was loaded with
the value popped (20h).
