/SS Pin wrong action of KL15

Hi, there. I am using SPI of KL15 MCU. I enable SSOE and MODFEN bit, but I found /SS will automatic drive high everytime I wrote into SPI0_D for more than one byte, in this case the slave IC will de-select, and receive 2 wrong command instead of a 2-bytes command. How can I use the /SS pin in this case ? Thank you!
