ACK Bit Output
The output value of the tenth bit (ACK bit) can be selected.
When the CRACK bit in the CECC2 register is 0 (inserted by program), the value of the CCRBAO bit
in the CCRB2 register is output as ACK data.
When the CRACK bit is 1 (inserted by hardware), ACK is output when the received Destination
address matches the address selected by the CRADRI1 or CRADRI2 register (own address). Table
