DS refers to HSTROBE. HAD refers to UHPI_HCNTL[0], UHPI_HCNTL[1], UHPI_HHWIL, and UHPI_HRW.
Max delay is a best case, assuming no delays due to resource conflicts between UHPI and dMAX or CPU. UHPI_HRDY should always
be used to indicate when an access is complete instead of relying on these parameters.
