The TUSB8044A supports the Billboard Alternate Mode Capability Descriptor. The dwAlternateModeVdo field in
the descriptor defaults to 0x00001C45 to align with DisplayPort Alt mode VDO with capabilities described in
Table 5. The default can be changed from OTP or EEPROM/SMbus. All dwAlternateModeVdo bits are
accessible from the EEPROM/SMbus but only some of the bits are accessible thru OTP.
