Hi expert:
I have some questions about OSPI:
in OSPI0/1 Timing Requirements – Tap DDR Mode
How to set this parameter: T = OSPI_RD_DATA_CAPTURE_REG[DELAY_FLD]

Hi expert:
I had read the document, but I'm still confused.
In this document, it said the OSPI_RD_DATA_CAPTURE_REG is set to delay the DQS.
But in TDA4VL-Q1 have a formula:
| 1.84 +(0.975T(1) ( R(2))) |
so why use this parameter to calculate the DDR Tap mode Setup time and Hold time.
