Transmit errors occur on the following situation.
• Shift operation starts before writing next transmit data to SIOTDB in external clock op-

eration.
If transmit errors occur during transmit operation, SIOSR<TXERR> is set to “1” imme-
diately after starting shift operation. And INTSIO interrupt request is generated after all
of the 8-bit data has been received.
If shift operation starts before writing data to SIOTDB after SIOCR1<SIOS> is set to
“1”, SIOSR<TXERR> is set immediately after starting shift operation. And INTSIO in-
terrupt request is generated after all of the 8-bit data has been received.
SO 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”
after the received data is read from SIORDB. In this case, SIOCR1<SIOS>, SIOSR reg-
ister, SIORDB register and SIOTDB register are initialized.
