14.6.5 Reception errors
reception result error flags are set in the UAnSTR register and a reception error interrupt request signal (INTUAnRE)
is output when an error occurs.
Errors during a receive operation are of three types: parity errors, framing errors, and overrun errors. Data
It is possible to ascertain which error occurred during reception by reading the contents of the UAnSTR register.
Clear the reception error flag by writing 0 to it after reading it.
Caution The reception end interrupt request signal (INTUAnR) and reception error interrupt request

reception ends normally. The INTUAnRE signal is generated and the INTUAnR signal is not
generated when a reception error occurs.
