hello， NXP developers，when i used the MCUXpresso Config Tools v12.1 to configure LPI2C as transfer mode, and then using LPI2C_MasterTransferNonBlocking API as actual  transmission interface, my code program stuck in irq_callback.Then, I used keil's call stack and obtained the following information.

I don't know where the problem is. Can you give me some help

Note: When I use polling mode,and using LPI2C_MasterTransferBlocking API is used as the actual transmission interface, the transfer process is correct. so I think the information in "lpi2c_master_transfer_t transfer" structure is correct.
