PIC18F47J13 FAMILY
27.2
PIC18F47J13 family devices have both a conventional
WDT circuit and a dedicated, Deep Sleep capable
Watchdog Timer. When enabled, the conventional
WDT operates in normal Run, Idle and Sleep modes.
This data sheet section describes the conventional
WDT circuit.
The dedicated, Deep Sleep capable WDT can only be
enabled in Deep Sleep mode. This timer is described in
Section 4.6.4
(DSWDT)”.
The conventional WDT is driven by the INTRC
oscillator. When the WDT is enabled, the clock source
is also enabled. The nominal WDT period is 4 ms and
has the same stability as the INTRC oscillator.
The 4 ms period of the WDT is multiplied by a 16-bit
postscaler. Any output of the WDT postscaler is
selected by a multiplexer, controlled by the WDTPS bits
in Configuration Register 2H. Available periods range
from about 4 ms to 135 seconds (2.25 minutes
depending
postscaler). The WDT and postscaler are cleared

27.2.1
The WDTCON register (Register 27-11) is a readable
and writable register. The SWDTEN bit enables or dis-
ables WDT operation. This allows software to override
the WDTEN Configuration bit and enable the WDT only
if it has been disabled by the Configuration bit.
LVDSTAT is a read-only status bit that is continuously
updated and provides information about the current
