After seven calls or six calls and one
interrupt, the stack looks like the figure
on
instructions will repeatedly place the
return addresses into the Program
Counter.
When the stack is full, the next call or
interrupt will set the Stack Pointer to
0x10. This is identical to address 0x00
so the stack will wrap. If the Overflow
Reset is enabled, a Reset will occur.
