10.2.5. Stack
A programmer’s stack can be located anywhere in the 256-byte data memory. The stack area is designated using
the Stack Pointer (SP, 0x81) SFR. The SP will point to the last location used. The next value pushed on the stack is
placed at SP+1 and then SP is incremented. A reset initializes the stack pointer to location 0x07. Therefore, the
first value pushed on the stack is placed at location 0x08, which is also the first register (R0) of register bank 1.
Thus, if more than one register bank is to be used, the SP should be initialized to a location in the data memory not
being used for data storage. The stack depth can extend up to 256 bytes.
The MCUs also have built-in hardware for a stack record. The stack record is a 32-bit shift register, where each
Push or increment SP pushes one record bit onto the register, and each Call or interrupt pushes two record bits onto
the register. (A Pop or decrement SP pops one record bit, and a Return pops two record bits, also.) The stack
record circuitry can also detect an overflow or underflow on the Stack, and can notify the debug software even with
the MCU running full-speed debug.
