MSPM0G3507: I2C Write abnormal for Multi-device address switching on one bus

Part Number: MSPM0G3507

Tool/software:

I currently have two DRIVERS on I2C0 at addresses 0X3C and 0x3f.

When I finished initializing the 0x3c device, ready to switch the address to 0x3f to write data, found that after switching the address of the first data is still 0x3c, did not switch the success of the 0x3f, but I look at the parameters of the variable is right is 0x3f.

What is the reason that the first packet of data for each switch of address stays at the previous address. i am developing based on mspm0_sdk_1_30_00_03 IAR.
