DP159 Retimer Register Programming - 2.1 English

The DP159 does not monitor the AUX transactions between the DisplayPort source and DisplayPort sink during link training, as a typical DisplayPort retimer would. Because of this the DisplayPort software driver handles the required DP159 configuration.

For more details on the programming sequence or the DP159 register details, see DP159 as DisplayPort Retimer.

The sequences of the DP159 retimer, handled in the DisplayPort driver, are summarized in the following sections:

• DP159 Initialization
• TP1 Interrupt Handler (TP1_Handler)
• TP23 Interrupt Handler (TP23_Handler)
• DP159 Re-Initialization
