tents, the received data is ignored while the SIO2SR<RXERR> is “1”.
Receive error processing
Receive errors occur on the following situation. To protect SIO2RDB and the shift register con-
• Shift operation is finished before reading out received data from SIO2RDB at
SIO2SR<RXF> is “1” in an external clock operation.
If receive error occurs, set the SIO2CR<SIOS> to “0” for reading the data that received
immediately before error occurence. And read the data from SIO2RDB. Data in shift register
(at errors occur) can be read by reading the SIO2RDB again.
When SIO2SR<RXERR> is cleared to “0” after reading the received data, SIO2SR<RXF> is
cleared to “0”.
After clearing SIO2CR<SIOS> to “0”, when 8-bit serial clock is input to
operation is stopped. To restart the receive operation, confirm that SIO2SR<SIOF> is cleared
to “0”.
If the receive error occurs, set the SIO2CR<SIOINH> to “1” for stopping the receive opera-
tion immediately. In this case, SIO2CR<SIOS>, SIO2SR register, SIO2RDB register and
SIO2TDB register are initialized.
