To configure the 256 KByte address range (default):
1.
Set jumper JP23 (callout 1) to position 1-2 (enables the parallel Flash memory).
2.
Set JP11 (callout 2) to position 1-2 to connect PMA17 to LED D4 only, and use
that microcontroller pin to control the LED.
Alternatively, remove jumper JP11 (disconnects PMA17 signal entirely).

To enable the support of multiple PICtail Plus Daughter Boards, the development board
maps selected I/Os to multiple PICtail Plus pins. In some cases, using certain daughter
boards may mean disabling some functionality on the development board. In general,
when the PICtail Plus connector is in use, these development board features are not
available:
