Hi, Sukumar,
Regarding the EOT and EOF, pls refer to section 27.7.3.2 Frame_delay and 27.7.3.3 Transfer_delay in UM11155.pdf.
The EOF setting means that SPI master will insert delay between each transmitting data, but the /CS remain LOW between two transfer, the Frame Delay time is defined in SPI Delay register.
The EOT setting means that SPI master will insert delay between each transmitting data, meanwhile the /CS is driven to HIGH between two transfer, the Transfer Delay time is defined in SPI Delay register. That the /CS is set high means that the transfer is completed.
Hope it can help you
