the number of pieces of data that could not be received. Execute the error handling, for example, by receiving data
again from the beginning of the transfer. Basically, an overrun error occurs when the internal software processing
cannot follow the data transfer speed. It is recommended to slow the transfer baud rate or modify the software to
execute flow control.
Note 1: If multiple interrupts are used in the INTRXD0 interrupt subroutine, the interrupt should be enabled after reading UART0SR
Figure 16-18 shows an example of the receiving process. Details of flag judgments in the processing are shown in
If any framing error or parity error is detected, the received data has erroneous value(s). Execute the error handling,
If any overrun error is detected, the receiving of one or more pieces of data is unfinished. It is impossible to determine
