26.6
PIC24FJ64GB004 family devices implement a JTAG
interface, which supports boundary scan device
testing.
26.7
PIC24FJ64GB004 family microcontrollers can be seri-
ally 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 cus-
tomers 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.

26.8
When MPLAB
in-circuit debugging functionality is enabled. This func-
tion allows simple debugging functions when used with
MPLAB IDE. Debugging functionality is controlled
through the PGECx (Emulation/Debug Clock) and
PGEDx (Emulation/Debug Data) pins.
To use the in-circuit debugger function of the device,
the design must implement ICSP connections to
MCLR, V
ignated by the ICS Configuration bits. In 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.
