LTC6811-1 Turning ON MOSFETs


I am trying to operate LTC6811-1 Battery monitoring IC with STM32F3 Microcontroller. I want to turn OFF a particular MOSFET in the cell balancing system in DC2259A  through SPI communication . What is the instruction algorithm /  frame format  for controlling the  Mosfet through spi  ?

Do you have any suggestion or solution for my case so that I can control mosfets for my cell balancing system.

Thank you in advance.
