关于Bus Acquiring

[djqlyy]

如果SPI做主机的话，有一段话：
Bus Acquiring
Sometimes you might want to send SPI transactions exclusively and continuously so that it takes as little time as possible. For this, you can use bus acquiring, which helps to suspend transactions (both polling or interrupt) to other devices until the bus is released.

which helps to suspend transactions to other devices until the bus is released.什么意思，挂起，暂停？？？我的英语不好，没理解这句话，谁能给解答一下吗？
