48.4.4 Data format (non ISO-7816)
Each data character is contained in a frame that includes a start bit and a stop bit. The rest
of the data format depends upon UARTx_C1[M], UARTx_C1[PE], UARTx_S2[MSBF],
and UARTx_C4[M10].
48.4.4.1 Eight-bit configuration
Clearing the UART_C1[M] configures the UART for 8-bit data characters, that is, eight
bits are memory mapped in UART_D. A frame with eight data bits has a total of 10 bits.
The most significant bit of the eight data bits can be used as an address mark to wake the
receiver. If that bit is used in this way, then it serves as an address or data indication,
leaving the remaining seven bits as actual data. When UART_C1[PE] is set, the 8th
databit is automatically calculated as the parity bit. Refer to the following table.
