简介(Introduction)
=======================

Bfx模块实现了AUTOSAR中需要的位操作，包括特定位的置位、清零、取状态值、左右移、按位取反等。

The Bfx module implements the bit operations required in AUTOSAR, including setting, clearing, getting the status value of specific bits, left and right shifting, and bitwise negation, etc.

功能描述(Functional Description)
=====================================


特性(Features)
------------------

初始化和shutdown(Initialization and shutdown)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Bfx库不需要初始化阶段。库函数可以在ECU初始化的第一步调用。

The Bfx library does not require an initialization stage. Library functions can be called in the first step of ECU initialization. 

Bfx库不需要shutdown操作阶段。

The Bfx library does not need a shutdown operation stage.

分区与共享(Partitioning and Sharing)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Bfx库应该以一种代码可以在不同内存分区中的调用者之间共享的方式实现。

The Bfx library should be implemented in such a way that its code can be shared among callers residing in different memory partitions.
