Descriptions of segments

Reference Guide

This segment and its length is normally defined in the linker command file by the 
command:

-Z(DATA)NEAR_HEAP+nn=start

where 

 is the length and 

 is the location.

For more information about dynamically allocated data and the heap, see The return 
address stack, page 43. For information about using the 

new

 and 

delete

 operators for 

a heap in near memory, see New and Delete operators, page 114.

NEAR_I

Holds non-zero initialized static and global 

_ _near

 variables.

DATA

Data. The address range is 

0x0–0xFFFF

.

Holds static and global 

_ _near

 variables that have been defined with non-zero initial 

values. 

When the 

-y

 compiler option is used, 

NEAR_C

 data (

_ _near

 or 

_ _tiny

) is located in 

this segment.

NEAR_ID

Holds 

_ _near

 variable initializers.

CODE

Flash. The address range is 

0x0–0x7FFFFF

.

Holds initial values for the variables located in the 

NEAR_I

 segment. These values are 

copied from 

NEAR_ID

 to 

NEAR_I

 during system initialization.
