RESETS
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
- Illegal Opcode Reset
- Uninitialized W Register Reset
- Security Reset
A simplified block diagram of the Reset module is
shown in Figure 6-1.
Any active source of reset will make the SYSRST
signal 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 bit
(RCON<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.

Note 1: This data sheet summarizes the features
of the dsPIC33FJ32GP202/204 and
dsPIC33FJ16GP304 family of devices. It
is not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to
Section 8. “Reset” (DS70192) of the
“dsPIC33F/PIC24H Family Reference
Manual”, which is available from the
(www.microchip.com).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
this data sheet for device-specific register
and bit information.
Note:
Refer to the specific peripheral section or
Section 3.0 “CPU” of this manual for
register Reset states.
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 is meaningful.
