term SSP (or A7) refers to the MSP address register. When M = 0 , the term
SSP (or A7) refers to the ISP address register. The active system stack pointer
system stack fills from high to low memory.
A subroutine call saves the program counter on the active system stack, and
the return restores it from the active system stack. During the processing of
traps and interrupts, both the program counter and the status register are
stack; conversely, user programs use the user stack pointer independently
To keep data on the system stack aligned for m a x i m u m efficiency, the active
mode. The term supervisor stack pointer (SSP) refers to the master or inter-
rupt stack pointers, depending on the state of the M bit. When M = 1, the

of supervisor code is independent of user code and the condition of the user

stack pointer is automatically decremented or incremented by two for all
byte-sized operands moved to or from the stack. In long-word-organized
