25.3.1
The Watchdog Timer has an optional Fixed Window
mode of operation. In this Windowed mode, CLRWDT
instructions can only reset the WDT during the last 1/4
of the programmed WDT period. A CLRWDT instruction
executed before that window causes a WDT Reset,
similar to a WDT time-out.
Windowed WDT mode is enabled by programming the
WINDIS Configuration bit (CW1<6>) to ‘0’.

complimentary methods to protect application code
from overwrites and erasures. These also help to
protect the device from inadvertent configuration
changes during run time.
25.4.1
For all devices in the PIC24FJ256GA110 family, the
on-chip program memory space is treated as a single
block, known as the General Segment (GS). Code

25.3.2
The WDT is enabled or disabled by the FWDTEN
Configuration bit. When the FWDTEN Configuration bit
is set, the WDT is always enabled.
The WDT can be optionally controlled in software when
the FWDTEN Configuration bit has been programmed
to ‘0’. The WDT is enabled in software by setting the
SWDTEN control bit (RCON<5>). The SWDTEN
control bit is cleared on any device Reset. The software
WDT option allows the user to enable the WDT for
critical code segments and disable the WDT during
non-critical segments for maximum power savings.
protection for this block is controlled by one Configura-
tion bit, GCP. This bit inhibits external reads and writes
to the program memory space. It has no direct effect in
normal execution mode.
Write protection is controlled by the GWRP bit in the
Configuration Word. When GWRP is programmed to
‘0’, internal write and erase operations to program
memory are blocked.
