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
• WDT: Watchdog Timer Reset
• TRAPR: Trap Conflict Reset
• IOPUWR: Illegal Opcode and Uninitialized W
A simplified block diagram of the Reset module is
shown in Figure 5-1.
Any active source of Reset will make the SYSRST sig-
nal 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 POR and unchanged by all other Resets.

Preliminary
All types of device Reset will set a corresponding status
bit in the RCON register to indicate the type of Reset
(see Register 5-1). A POR will clear all bits, except for
the POR bit (RCON<0>), that are set. The user 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:
Note:
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.
