LP-MSPM0L1306: about power saving for I2C controller in LP-MSPM0L1306

Part Number: LP-MSPM0L1306

Dear Sir,

I want to know if it is possible for the following case.

.  set I2C be controller mode with 400k and do communication with a target device.

. after finishing, do

DL_I2C_disablePower(I2C_INST)

DL_I2C_disableController(I2C_INST);

DL_SYSCTL_setPowerPolicySTANDBY0();

__WFI();  //wak up from GPIO

DL_SYSCTL_setPowerPolicyRUN0SLEEP0();

DL_I2C_ensablePower(I2C_INST)

DL_I2C_enableController(I2C_INST);

 

It seems that it doesn't work correctly. How can I reinit after wakeup?

Thanks
