芯片手册的这句话怎么翻译，，backpressure。。

The serial peripheral interface is full-duplex and does not support backpressure. It
supports SPI clock phase bit, CPHA = 1, and SPI clock polarity bit, CPOL = 0.
我只知道全双工，，剩下的那，谢谢。。。。

Back pressure in information technology

The term is also used ana**usly in the field of information technology to describe the build-up of data behind an I/O switch if the buffers are full and incapable of receiving any more data; the transmitting device halts the sending of data packets until the buffers have been emptied and are once more capable of storing information.
