T7 is the maximum Ts value requested by the SPI slave. The SPI master shall initiate a data transfer before the T1+T7, if the slave sends a T7 value different from 'FFFFFF'.

54685e5148bbff6300c41deae946f3c9 | 103 713 | 7.2.4.1 Introduction | As a slave SPI module is normally always ready for an access from the master when selected by SPI_NSS assertion, the slave configures its SPI module in disabled state before asserting SPI_NSS for a MAC access request. This is necessary in order to avoid self-selection e.g. driving MISO in contention with MISO signals o... |
