6.9.1
ILLEGAL OPCODE RESET
A device Reset is generated if the device attempts to
execute an illegal opcode value that is fetched from
program memory.
The illegal opcode Reset function can prevent the
device from executing program memory sections that
are used to store constant data. To take advantage of
the illegal opcode Reset, use only the lower 16 bits of
each program memory section to store the data values.
The upper 8 bits should be programmed with 3Fh,
which is an illegal opcode value.
6.9.2
UNINITIALIZED W REGISTER
RESET
Any attempts to use the uninitialized W register as an
address pointer will Reset the device. The W register
array (with the exception of W15) is cleared during all
Resets and is considered uninitialized until written to.
6.9.3
SECURITY RESET
If a Program Flow Change (PFC) or Vector Flow
Change (VFC) targets a restricted location in a
protected segment (Boot and Secure Segment), that
operation will cause a security Reset.
The PFC occurs when the Program Counter is
reloaded as a result of a Call, Jump, Computed Jump,
Return, Return from Subroutine, or other form of
branch instruction.
The VFC occurs when the Program Counter is
reloaded with an Interrupt or Trap vector.

Security Reset.

Using the RCON Status Bits
The user application can read the Reset Control
(RCON) register after any device Reset to determine
the cause of the Reset.
Table 6-3 provides a summary of Reset flag bit
operation.
TABLE 6-3:
RESET FLAG BIT OPERATION
Note:
The status bits in the RCON register
should be cleared after they are read so
that the next RCON register value after a
device Reset will be meaningful.
