Abstract
The present disclosure generally relates to reducing time for interface transmitter training based upon an assumed identify of the training partner. It is unlikely for a drive PHY to link up with multiple PHYs per power cycle. Therefore, it is a fair assumption that when there is no power loss, the drive PHY is connected to the same host device. The drive can therefore change its behavior based on the assumed identity of the host from previously exchanged identify frames, if the previously used training algorithm was sufficient for interface transmitter training for the particular host. The drive will go directly to the correct training algorithm without the need to do a PHY reset using a training algorithm that is tailored to the host and thus reduce interface transmitter training time.
