Transmit errors occur on the following situation.
• Shift operation starts before writing next transmit data to SIO2TDB in external clock op-

eration.
If transmit errors occur during transmit operation, SIO2SR<TXERR> is set to “1” im-
mediately after starting shift operation. And INTSIO2 interrupt request is generated af-
ter all of the 8-bit data has been received.
If shift operation starts before writing data to SIO2TDB after SIO2CR<SIOS> is set to
“1”, SIO2SR<TXERR> is set immediately after starting shift operation. And INTSIO2
interrupt request is generated after all of the 8-bit data has been received.
SO2 pin is kept in high level when SIO2SR<TXERR> is set to “1”. When transmit error
occurs, transmit operation must be forcibly stop by writing SIO2CR<SIOINH> to “1”
after the received data is read from SIO2RDB. In this case, SIO2CR<SIOS>, SIO2SR
register, SIO2RDB register and SIO2TDB register are initialized.
