Reference Manual”, which is available
from the Microchip web site
(www.microchip.com/PIC32).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.

controls the device Master Reset signal, SYSRST. The
following is a list of device Reset sources:
• POR: Power-on Reset
• MCLR: Master Clear Reset pin
• SWR: Software Reset
• WDTR: Watchdog Timer Reset
• BOR: Brown-out Reset
• CMR: Configuration Mismatch Reset
A simplified block diagram of the Reset module is
illustrated in Figure 6-1.
