4.13.2 Exception Stack Frame
4-38
MOTOROLA
During exception processing, the contents of the program counter and condition code
register are stacked at a location pointed to by SK:SP. Unless it is altered during ex-
ception processing, the stacked PK:PC value is the address of the next instruction in
the current instruction stream, plus $0006. Figure 4-6 shows the exception stack
frame.
