The Reset module combines all Reset sources and
controls the device Master Reset Signal, SYSRST. The
following is a list of device Reset sources:
• POR: Power-on Reset
• MCLR: Pin Reset
• SWR: RESET Instruction
• WDTR: Watchdog Timer Reset
• BOR: Brown-out Reset
• Low-Power BOR/Deep Sleep BOR
• TRAPR: Trap Conflict Reset
• IOPUWR: Illegal Opcode Reset
• UWR: Uninitialized W Register Reset

Glitch Filter
Any active source of Reset will make the SYSRST
signal active. Many registers associated with the CPU
and peripherals are forced to a known Reset state.
Most registers are unaffected by a Reset; their status is
unknown on Power-on Reset (POR) and unchanged by
all other Resets.
All types of device Reset will set a corresponding status
bit in the RCON register to indicate the type of Reset
(see
the BOR and POR bits (RCON<1:0>) which are set.
The user may set or clear any bit at any time during
code execution. The RCON bits only serve as status
bits. Setting a particular Reset status bit in software will
not cause a device Reset to occur.
The RCON register also has other bits associated with
the Watchdog Timer (WDT) and device power-saving
states. The function of these bits is discussed in other
sections of this manual.

Refer to the specific peripheral or CPU
section of this manual for register Reset
states.
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.
