你看的IIC协议中文版吧?感觉这翻译的让我读起来好憋屈阿,还是看英文吧。
第一句应该指的是主机往从机写数 ...

我是对照着看的,感觉这个中文版的看起来很恼人,原版在下面,红色部分,应该是你讲的那个意思。但是下面的 first byte to follow 和
clocked out of the slave比较难理解。
If a slave-receiver does acknowledge the slave address but, some time later in the transfer cannot receive any
more data bytes, the master must again abort the transfer.
This is indicated by the slave generating the
not-acknowledge on the first byte to follow. The slave
leaves the data line HIGH and the master generates a
STOP or a repeated START condition.
If a master-receiver is involved in a transfer, it must signal
the end of data to the slave- transmitter by not generating
an acknowledge on the last byte that was clocked out of
the slave. The slave-transmitter must release the data line
to allow the master to generate a STOP or repeated
START condition. |
