Figure 14. MAXQ7665B Memory Map
A pseudo-Von Neumann memory map can also be
enabled. This places the utility ROM, code, and data
memory into a single contiguous memory map. This is
useful for applications that require dynamic program
modification or unique memory configurations.
Stack Memory
A 16-bit-wide x 16 deep internal hardware stack pro-
vides storage for program return addresses and gener-
al-purpose use. The stack is used automatically by the
processor when the CALL, RET, and RETI instructions
are executed and interrupts serviced. The stack can
also be used explicitly to store and retrieve data by
using the PUSH, POP, and POPI instructions.
On reset, the stack pointer, SP, initializes to the top of the
stack (0Fh). The CALL, PUSH, and interrupt-vectoring
operations increment SP, then store a value at the location
pointed to by SP. The RET, RETI, POP, and POPI opera-
tions retrieve the value at SP and then decrement SP.
Utility ROM
The utility ROM is an 8KB (4K x 16) block of internal
ROM memory that defaults to a starting address of
8000h. The utility ROM consists of subroutines that can
be called from application software. These include:
In-system programming (bootstrap loader) over JTAG
In-circuit debug routines
User-callable routines for in-application flash pro-
gramming and fast table lookup
