Hi,
The TRM describes this case:

However, we are not sure if this works in the usual SPI duplex mode where the TDA4VM SPI master outputs the write data to MOSI (DQ0) and simultaneously reads the data to MISO (DQ1).
(We running out of standard SPI ports on the right power/voltage domain. We do not need Flash on the OSPI ports.)
Many thanks in advance!
