Figure 14 shows the sequence of events during the transmission of a Data Burst.
上图展示了在一次传输过程中时序

1.HS_PREPARE

Time that the transmitter drives the Data Lane LP-00 Line state immediately before the HS-0 Line state starting the HS transmission
在开始传输之前，Data Lane的状态从LP-00到HS状态，需要准备的时间

2.HS_ZERO

the transmitter drives the HS-0 state prior to transmitting the Sync sequence
在HS-PREPARE之后，在HS-SYNC之前（3个bit）的时间

3.HS_TRAIL

Time that the transmitter drives the flipped differential state after last payload data bit of a HS transmission burst
在HS传输模式下，最后一个有效payload的bit位之后的等待时间

4.EOT

Transmitted time interval from the start of THS-TRAIL or TCLK-TRAIL, to the start of the LP-11 state following a HS burst.
从HS-TRAIL开始到进入LP-11的时间

5.HS_EXIT

Time that the transmitter drives LP-11 following a HS burst.
在HS传输之后，持续LP-11的时间
