Figure 3.12.27 Transmit Data Retention Time When Terminating Transmission/Reception
Note: If the transfer mode is changed during transmit/receive operation, the contents of SBI0DBR will be lost.
If it is necessary to change the transfer mode, first terminate transmission/reception (by writing a 0 to
SBI0CR1<SIOS>) and read out the last received data.
Write transmit data (a)
