Description
Reserved
These bits are always read as 0. The write value should
always be 0.
LS Threshold
This field contains a value to be compared with the FR bit
prior to the beginning of low-speed transaction. The
transaction is started only when the FR bit value is beyond
the value of the list. The value is calculated by HCD
considering the transmission and set-up overhead.
