Hardware triggered LPSPI transmission for I.MX RT 1020

I plan to use LPSPI to access the esternal ADC. I would like to have a sampling rate at 500 KHz. I find the module XBARA can provide a  hardware trigger for LPSPI. 


My question is that if I use this hardware trigger for LPSPI. Do I need to send software command to start SPI communication?

How many transmission would happen after one hardware trigger? 


Best regards,
