Hello Cheryl,

1) You have to use the R5FSS0_0_MBOX_READ_DONE_ACK.
2) This is present in secure_ipc_notify driver in the mcuplus SDK folder

I couldn't find this register even after searching the chip manual. I even extracted the register address from the SDK package, but still couldn't find it in the chip manual

Hello Cheryl,

We can take it as feedback for TRM, for now please refer to the SDK offset and utilize that.
