EEPROM_I

Holds non-zero initialized static and global 

_ _eeprom

 variables.

XDATA

EEPROM.

Holds static and global 

_ _eeprom

 variables that have been defined with non-zero initial 

values. This segment is not copied to EEPROM during system startup. Instead it is used 
for programming the EEPROM during the download of the code.

Use the command line option 

--eeprom_size

 to set the address range for this segment; 

see --eeprom_size, page 180, for additional information.

EEPROM_N

Holds 

_ _no_init

 static and global 

_ _eeprom

 variables.

XDATA

EEPROM.

Holds static and global 

_ _eeprom

 variables that will not be initialized during the 

download of the code to the EEPROM. These variables have been declared 

_ _no_init

.

Use the command line option 

--eeprom_size

 to set the address range for this segment; 

see --eeprom_size, page 180, for additional information.

FARCODE

Holds 

_ _farfunc

 program code.

CODE

Flash. The address range is
