2.7
If an ICSP compliant emulator is selected as a debug-
ger, it automatically initializes all of the A/D input pins
(ANx) as “digital” pins. Depending on the particular
device, this is done by setting all bits in the ADnPCFG
register(s), or clearing all bit in the ANSx registers.
All PIC24F devices will have either one or more
ADnPCFG registers or several ANSx registers (one for
each port); no device will have both. Refer to
Section 21.0 “10-Bit High-Speed A/D Converter” for
more specific information.
The bits in these registers that correspond to the A/D
pins that initialized the emulator must not be changed
by
communication errors will result between the debugger
and the device.

If your application needs to use certain A/D pins as
analog input pins during the debug session, the user
application must modify the appropriate bits during
initialization of the ADC module, as follows:
• For devices with an ADnPCFG register, clear the
• For devices with ANSx registers, set the bits
When a Microchip debugger/emulator is used as a
programmer, the user application firmware must
correctly configure the ADnPCFG or ANSx registers.
Automatic initialization of this register is only done
during debugger operation. Failure to correctly
configure the register(s) will result in all A/D pins being
recognized as analog input pins, resulting in the port
value being read as a logic '0', which may affect user
application functionality.
