8.2
A Reset is not a true exception because the interrupt
controller is not involved in the Reset process. The pro-
cessor initializes its registers in response to a Reset
which forces the PC to zero. The processor then begins
program execution at location 0x000000. A GOTO
instruction is stored in the first program memory loca-
tion immediately followed by the address target for the
GOTO instruction. The processor executes the GOTO to
the specified address and then begins operation at the
specified target (start) address.
8.2.1
In addition to external Reset and Power-on Reset
(POR), these sources of error conditions ‘trap’ to the
Reset vector:
• Watchdog Time-out:
• Uninitialized W Register Trap:
• Illegal Instruction Trap:
• Brown-out Reset (BOR):
• Trap Lockout:
The watchdog has timed out, indicating that the
processor is no longer executing the correct flow
of code.
An attempt to use an uninitialized W register as
an Address Pointer causes a Reset.
Attempted execution of any unused opcodes
results in an illegal instruction trap. Note that a
fetch of an illegal instruction does not result in an
illegal instruction trap if that instruction is flushed
prior to execution due to a flow change.
A momentary dip in the power supply to the
device has been detected which may result in
malfunction.
Occurrence of multiple trap conditions
simultaneously causes a Reset.
