write bus

Realize the interface between PCI9054 and the PCI bus, including the bus arbitration, read and write of the registers, the configuration of the EEPROM, the DMA transfer, interrupt response and so on.

实现PCI9054与计算机PCI总线的接口，包括总线仲裁，寄存器读写操作，EEPROM的配置和下载，DMA传输，中断响应等功能。

During the analysis of system simulation, the address bus, the data bus and the write/ read signals are explained in detail.

在系统仿真分析中，对地址总线、数据总线以及读写信号进行了详细的说明。

We will use an existing bus named twprocsvr_bus to create a new destination ( queue) where you want to read and write messages.

我们将使用一个名为twprocsvr bus的现有总线来创建一个新目标（队列），以便在其中读写消息。

And discussed through I C bus and EEPROM read and write operation to achieve the parameters' preservation and read.

而且讨论了如何通过I~2C总线与EEPROM进行读写操作进而实现参数的保存和读取。

Your write system call will be interrupted by the bus error signal SIGBUS, because you performed a bad memory access.

此时write系统调用会被进程接收到的SIGBUS信号中断，因为当前进程访问了非法内存地址。
