6.9.2
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
If a Program Flow Change (PFC) or Vector Flow
Change (VFC) targets a restricted location in a pro-
tected 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.

The user application can read the Reset Control
(RCON) register after any device Reset to determine
the cause of the Reset.

operation.
Note:
Using the RCON Status Bits
provides a summary of Reset flag bit
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.
