+ICF是告诉编译器：你的程序、变量、代码应该放到芯片哪一块内存里的“地图”文件。
 
-在 `IAR` 编译环境下，`__section_start("name")` 是一个 **内置宏**，它返回指定段（section）`name` 的起始地址。通常用于获取某个内存段的起始地址，比如某个代码段、数据段、或者自己定义的特殊段。

-**举例**
+| 功能          | ICF 术语                            |
+| ------------- | ----------------------------------- |
+| 定义内存      | `define region`                     |
+| 放置代码/数据 | `place in region`                   |
+| 放中断表      | `place at start of ROM { .intvec }` |
+| 特殊变量段    | `.noinit`                           |

+/* 开始放置内容 */
+initialize by copy { readwrite };
+do not initialize  { section .noinit };   /* .noinit 不初始化 */
 
-ICF（**IAR Linker Configuration File**）用于定义程序的内存布局，包括代码、数据、堆栈等在内存中的分布。
-
-**变量分配到特定内存区域的方法**：
-
-你可以通过修改 `.icf` 文件中的 `define block` 和 `place in` 语句来控制变量在内存中的分布。
-
-**示例（将某段变量放到特定内存区域）：**
-
-```
-icf复制编辑define region MY_RAM = mem:[from 0x20010000 to 0x20010FFF];
-define block my_section with alignment = 8 { section .mydata };
-place in MY_RAM { block my_section };
-```
+/* Flash（ROM）放置策略 */
+place at start of ROM_region { readonly section .intvec };  /* 中断向量表 */
+place in ROM_region { readonly };   /* 代码和常量 */
 
-然后在代码中定义变量时，使用 `__attribute__((section(".mydata")))` 或 IAR 的 `__section`：
+/* SRAM（RAM）放置策略 */
+place in RAM_region { readwrite,                          /* 初始化变量 */
+                      block HEAP,                         /* 堆 */
+                      block CSTACK,                       /* 栈 */
+                      section .noinit };                  /* 不初始化区 */
