The amount of emulator- and target-supplied memory will display in “Emulator
Supplied” and “Target Supplied” under “ICE Memory Mapping”, respectively.
In order to communicate with the target board memory, you will need to set up the
external memory interface under “Target 16-Bit Access Mode”. Select the access mode
(Word Write, Byte Select or Byte Write) and a table read/write Wait time in cycles. For
more information, see the MEMCON register under the External Memory Interface
section of the device data sheet.
5.4.3.2
EXTERNAL PROGRAM MEMORY ON TARGET BOARD
To use a combination of emulator and target memory, or all target memory, select “On
Target Board” under “External (Off-Chip) Program Memory”. The amount of emulator-
and target-supplied memory will display in “Emulator Supplied” and “Target Supplied”
under “ICE Memory Mapping”, respectively.
In order to communicate with the target board memory, you will need to set up the
external memory interface under “Target 16-Bit Access Mode”. Select the access mode
(Word Write, Byte Select or Byte Write) and a table read/write Wait time in cycles. For
more information, see the MEMCON register under the External Memory Interface
section of the device data sheet.

PIC18C601/801 CHIP SELECT SETUP
For PIC18C601/801 devices, you should specify values for the CSEL2 and CSELIO
registers. See the device data sheet for more on these registers.
