When the UiERE bit in the UiC1 register (i=0 to 4) is set to "1", the parity error signal can be output.
The parity error signal is output when a parity error is detected upon receiving data. TxDi outputs an
"L" signal in the timing shown in Figure 16.31. When reading the UiRB register during a parity error
output, the PER bit in the UiRB register is set to "0" and TxDi again outputs an "H" signal simulta-
neously.
To determine whether the parity error signal is output, the port that shares a pin with RxDi is read by
using a transmit complete interrupt routine.
