On reset, the stack pointer, SP, initializes to the top of
the stack (0Fh). The CALL, PUSH, and interrupt-vector-
ing operations increment SP, then store a value at the
location pointed to by SP. The RET, RETI, POP, and
POPI operations retrieve the value at SP and then
decrement SP.
The utility ROM is a 4KB 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 the following:
• In-system programming (bootstrap loader) using
• In-circuit debug routines

Following any reset, execution begins in the utility ROM.
The ROM software determines whether the program
execution should immediately jump to location 0000h,
the start of user-application code, or to one of the spe-
cial routines mentioned. Routines within the utility ROM
are user-accessible and can be called as subroutines
by the application software. More information on the
utility ROM contents is contained in the MAXQ Family
