After reset
Undefined
Note1: When writing transmitted data, start from the MSB (bit 7).Receiving data is placed from LSB(bit0).
Note2: SBIDBR can’t be read the written data because of it has buffer for writing and buffer for reading
individually.Therefore Read modify write instruction (e.g.“BIT” instruction ) is prohibitted.
Note3:Written data to SBIDBR is cleared by INTSBI signal.
