参数“io access time”是什么意思？关于CY8C95xxA IO扩展器

2.485毫秒是最坏情况下的最大IO访问时间。
谢谢，

  2.485 ms is the worst case maximum IO Access time.

谢谢你的回复。但这并不能定义“IO访问时间”指的是什么…
-芯片的时间到一个I2C请求…？？？？
-芯片读取一个PIN的时间（以及对I2C读取请求的响应延迟）…？
-芯片写入PIN的时间（在收到端口设置命令之后）…？？
-…

  Thanks for replying. But that doesn't define what "IO Access time" refers to...
 
- time for chip to ACK an I2C request....???
- time for chip to read a pin (and consequent response delay to an I2C read request)...?
- time for chip to write to pin (after having received a port set command)..??
- ...

IO访问时间平均值
-芯片I2C数据包从开始到结束的时钟拉伸要求完成端口读取I2C数据读取引脚的时间
-芯片写的I2C引脚从分组开始到结束的时钟拉伸要求完成端口编写I2C数据包的时间
谢谢，

     以下为原文
  IO Access Time means
 
- time for chip to read a pin from start of I2C packet to end of I2C packet with clock stretching required to perform a port read
- time for chip to write to pin from start of I2C packet to end of I2C packet with clock stretching required to perform a port write
