RAM variables can be arranged in the defined order. The procedure is shown below. (1) In C source, use seginit pragma and segnoinit pragma to group RAM variables. ・Place a variable with initialization to a desired segment using the seginit pragma. ・Place a variable without initialization to a desired segment using the seginit pragma. ・Define each segment name with a unique name.
(Example for writing seginit pragma and segnoinit pragma) --- file1.c --- #pragma seginit "file1_ram1" int gi1 = 0x1234; int gi2 = 0x3456; #pragma seginit
#pragma segnoinit "file1_ram2" int gi3; int gi4; #pragma segnoinit
(2) Specify the assigned segment with the target option of IDEU8. Select [Project] -> [Options] -> [Target...], and display the [Segment] tab in the [Target Option] dialog, and set the followings.
(1) Check [DATA segment to assign with priority], and specify segment in the [Specify segment] field.
<Example on specifying segment> 0e000h file1_ram1 file1_ram2
(2) Check [Specify segment assigning order], and specify segment in the [Specify segment] field.
<Example on specifying segment> (file1_ram1 file1_ram2)
When specified as (1) and (2) above, RAM variables are assigned in the order of file1_ram1 and file1_ram2 after 0E000H address.
