„Emergency Reset

It is possible to shut down communication. For a forced reset, the SCnSBOS flag and the SCnSBIOS flag of the SCnMD1 register should be set to "0" (SBO pin : port, input data : "1" input). At forced reset, the status registers (the SCnBRKF flag of the SCnMD2 register, all flags of the SCnMD3 register) are initialized as they are set at reset, but the control register holds the setting value.

„Last Bit of Transfer Data

Table 11-3-4 shows the data output holding period of the last bit at transmission, and the minimum data input period of the last bit at reception. After data output holding period of the last bit, "H" is output.

„Other Control Flag Setup

Table 11-3-5 shows flags that are not used at clock synchronous communication. So, they are not needed to set or monitor.
