Transmit error processing
Transmit errors occur on the following situation.

Figure 11-8 Hold Time of the End of Transmit Mode
• Shift operation starts before writing next transmit data to SIOTDB in external clock opera-
tion.
If transmit errors occur during transmit operation, SIOSR<TXERR> is set to “1” immedi-
ately after starting shift operation. Synchronizing with the next serial clock falling edge,
INTSIO interrupt request is generated.
If shift operation starts before writing data to SIOTDB after SIOCR1<SIOS> is set to “1”,
SIOSR<TXERR> is set to “1” immediately after shift operation is started and then INTSIO
interrupt request is generated.
SIO pin is kept in high level when SIOSR<TXERR> is set to “1”. When transmit error
occurs, transmit operation must be forcibly stop by writing SIOCR1<SIOINH> to “1”. In
this case, SIOCR1<SIOS>, SIOSR register, SIORDB register and SIOTDB register are ini-
tialized.
