INTERRUPTS
MC68HC05J5A
4-2
REV 2.1
An RTI instruction is used to signify when the interrupt software service routine is
completed. The RTI instruction causes the register contents to be recovered from
the stack and normal processing to resume at the next instruction that was to be
executed when the interrupt took place. Figure 4-1 shows the sequence of events
that occur during interrupt processing.

4.2
RESET INTERRUPT SEQUENCE
The RESET function is not in the strictest sense an interrupt; however, it is acted
upon in a similar manner as shown in Figure 4-1. A low level input on the RESET
pin or an internally generated RST signal causes the program to vector to its start-
ing address which is specied by the contents of memory locations $0FFE and
$0FFF. The I-bit in the condition code register is also set.
