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
• BOR: Brown-out Reset
• MCLR: Master Clear Pin Reset
• SWR: RESET Instruction
• WDTO: Watchdog Timer Reset
• CM: Configuration Mismatch Reset
• TRAPR: Trap Conflict Reset
• IOPUWR: Illegal Condition Device Reset

A simplified block diagram of the Reset module is

Any active source of Reset will make the SYSRST sig-
nal active. On system Reset, some of the registers
associated with the CPU and peripherals are forced to
a known Reset state and some are unaffected.
All types of device Reset sets a corresponding status
bit in the RCON register to indicate the type of Reset
(see
A POR clears all the bits, except for the POR and BOR
bits (RCON<1:0>), that are set. The user application
can 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 does
not cause a device Reset to occur.
The RCON register also has other bits associated with
the Watchdog Timer and device power-saving states.
The function of these bits is discussed in other sections
of this manual.

Refer to the specific peripheral section or
Section 4.0 “Memory Organization”
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 is meaningful.
