Preliminary
8 bits. The counter is incremented each time an
instruction or data is fetched from the program
memory.
Stack pointer
The stack pointer is an 8-bit register which is
used to control the addressing of the vari-
able-length stack. The stack pointer is auto-
matically incremented and decremented under
control of the microprocessor to perform stack
manipulations under direction of either the
program or interrupt (NMI and IRQ). The stack
allows simple implementation of nested sub-
routines and multiple level interrupts. The
stack pointer is initialized by the user s soft-
ware.
