PIC24FV32KA304 FAMILY
26.4
In PIC24FV32KA304 family devices, in addition to the
WDT module, a DSWDT module is present which runs
while the device is in Deep Sleep, if enabled. It is
driven by either the SOSC or LPRC oscillator. The
clock source is selected by the Configuration bit,
DSWCKSEL (FDS<4>).
The DSWDT can be configured to generate a time-out
at 2.1 ms to 25.7 days by selecting the respective
postscaler. The postscaler can be selected by the
Configuration
When the DSWDT is enabled, the clock source is also
enabled.
DSWDT is one of the sources that can wake-up the
device from Deep Sleep mode.
26.5
For all devices in the PIC24FV32KA304 family, code
protection for the boot segment is controlled by the
Configuration bit, BSS0, and the general segment by
the Configuration bit, GSS0. These bits inhibit external
reads and writes to the program memory space This
has no direct effect in normal execution mode.
Write protection is controlled by bit, BWRP, for the boot
segment and bit, GWRP, for the general segment in the
Configuration Word. When these bits are programmed
to ‘0’, internal write and erase operations to program
memory are blocked.

26.6
PIC24FV32KA304 family microcontrollers can be
serially programmed while in the end application circuit.
This is simply done with two lines for clock (PGECx)
and data (PGEDx) and three other lines for power,
ground and the programming voltage. This allows
customers to manufacture boards with unprogrammed
devices and then program the microcontroller just
before shipping the product. This also allows the most
recent firmware or a custom firmware to be
programmed.
26.7
When MPLAB
PICkit™ 3 is selected as a debugger, the in-circuit
debugging functionality is enabled. This function allows
simple
MPLAB IDE. Debugging functionality is controlled
through the PGECx and PGEDx pins.
To use the in-circuit debugger function of the device,
the design must implement ICSP connections to
MCLR, V
addition, when the feature is enabled, some of the
resources are not available for general use. These
resources include the first 80 bytes of data RAM and
two I/O pins.
