Memories to Program

If “Erase All Before Program” is selected as shown in “Freeze Peripherals”, then all device memory will be erased before programming. To select specific memories to program after erase, check the specific memory type. To preserve the value of memory of different types, check to preserve that memory type and check the specific memory type; checking “Preserve Memory” writes the current contents to a buffer before erasing, and checking “Memory” writes the contents back into that memory after erasing, where Memory is the type of memory, such as EEPROM.

Table: Memories to Program Option Category
Auto select memories and ranges	Allow ICD 4 to Select Memories - The debugger uses your selected device and default settings to determine what to program. Manually select memories and ranges - You select the type and range of memory to program (see below).
Configuration Memory	Check to program Configuration Memory. This is always programmed in Debug mode.
Boot Flash	Check to program Boot Flash. This is always programmed in Debug mode.
EEPROM	Check to program EEPROM memory.
ID	Check to program the user ID.
Program Memory	Check to program the target program memory range specified below.
Program Memory Range(s) (hex)	The starting and ending hex address range(s) in program memory for programming, reading, or verification. Ranges must be separated by a comma (e.g., 0-ff, 200-2ff). Ranges must be aligned on a 0x800 address boundary. Note: The address range does not apply to the Erase function. The Erase function will erase all data on the device.
Preserve Program Memory	Check to not program the target program memory range specified below. Ensure that code is NOT code protected.
Preserve Program Memory Range(s) (hex)	The starting and ending hex address range(s) in target program memory to preserve when programming, reading, or verifying. This memory is read from the target and overlayed with existing MPLAB X IDE memory.
Preserve Memory	Check to preserve Memory for reprogramming, where Memory is the type of memory. Types include: EEPROM, ID, Boot Flash, and Auxiliary. Ensure that code is NOT code protected.
Preserve Memory Range(s) (hex)*	The starting and ending hex address range in target Memory to preserve when programming, reading, or verifying. Memory is the type of memory, which includes EEPROM, ID, Boot Flash, and Auxiliary. This memory is read from the target and overlayed with existing MPLAB X IDE memory. Ensure that code is NOT code protected.
* If you receive a programming error due to an incorrect range, ensure the range does not exceed available/remaining device memory.

Auto select memories and ranges

Allow ICD 4 to Select Memories - The debugger uses your selected device and default settings to determine what to program.

Manually select memories and ranges - You select the type and range of memory to program (see below).

Configuration Memory

Check to program Configuration Memory. This is always programmed in Debug mode.

Boot Flash

Check to program Boot Flash. This is always programmed in Debug mode.

EEPROM

Check to program EEPROM memory.

Check to program the user ID.

Program Memory

Check to program the target program memory range specified below.

Program Memory Range(s) (hex)

The starting and ending hex address range(s) in program memory for programming, reading, or verification. Ranges must be separated by a comma (e.g., 0-ff, 200-2ff). Ranges must be aligned on a 0x800 address boundary.

Note: The address range does not apply to the Erase function. The Erase function will erase all data on the device.

Preserve Program
Memory

Check to not program the target program memory range specified below.

Ensure that code is NOT code protected.

Preserve Program
Memory Range(s) (hex)

The starting and ending hex address range(s) in target program memory to preserve when programming, reading, or verifying.

This memory is read from the target and overlayed with existing MPLAB X IDE memory.

Preserve Memory

Check to preserve Memory for reprogramming, where Memory is the type of memory. Types include: EEPROM, ID, Boot Flash, and Auxiliary.

Ensure that code is NOT code protected.

Preserve Memory Range(s) (hex)*

The starting and ending hex address range in target Memory to preserve when programming, reading, or verifying. Memory is the type of memory, which includes EEPROM, ID, Boot Flash, and Auxiliary.

This memory is read from the target and overlayed with existing MPLAB X IDE memory.

Ensure that code is NOT code protected.

* If you receive a programming error due to an incorrect range, ensure the range does not exceed available/remaining device memory.
