24.2
For PIC18F87J11 Family devices, the 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 multiplexor, controlled by the WDTPS bits
in Configuration Register 2H. Available periods range
from about 4 ms to 135 seconds (2.25 minutes
depending on voltage, temperature and WDT post-
scaler). The WDT and postscaler are cleared whenever
a SLEEP or CLRWDT instruction is executed, or a clock
failure (primary or Timer1 oscillator) has occurred.

24.2.1
The WDTCON register (Register 24-9) 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.
The ADSHR bit selects which SFRs are currently
selected and accessible. See Section 5.3.4.1 “Shared
Address SFRs” for additional details.
The LVDSTAT is a read-only status bit which is continu-
ously updated and provides information about the current
level of V
