Chapter 6 Interrupt (S12XINTV2)
6.4.5
The XINT module supports three system reset exception request types (for details please refer to the Clock
and Reset Generator module (CRG)):
6.4.6
The priority (from highest to lowest) and address of all exception vectors issued by the XINT module upon
request by the CPU is shown in
than maskable interrupts. Please note that between the three software interrupts (Unimplemented op-code
trap request, SWI/BGND request, SYS request) there is no real priority defined because they cannot occur
simultaneously (the S12XCPU executes one instruction at a time).
1. 16 bits vector address based
2. only implemented if device features both a Memory Protection Unit (MPU) and an XGATE co-processor
3. only implemented if device features a Memory Protection Unit (MPU)

1. Pin reset, power-on reset, low-voltage reset, or illegal address reset
2. Clock monitor reset request
3. COP watchdog reset request

Reset Exception Requests
Exception Priority
Care must be taken to ensure that all exception requests remain active until
the system begins execution of the applicable service routine; otherwise, the
exception request may not get processed at all or the result may be a
spurious interrupt request (vector at address (vector base + 0x0010)).

Pin reset, power-on reset, low-voltage reset, illegal address reset
Clock monitor reset
COP watchdog reset
Unimplemented op-code trap
Software interrupt instruction (SWI) or BDM vector request

configuration registers, in descending order)
