45.4.5 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 C1[M], C1[PE], S2[MSBF], and C4[M10].
45.4.5.1 Eight-bit configuration
Clearing C1[M] configures the UART for 8-bit data characters, that is, eight bits are
memory mapped in 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 the most significant bit is used in this way, then it serves as an address or data
indication, leaving the remaining seven bits as actual data. When C1[PE] is set, the eighth
data bit is automatically calculated as the parity bit. See the following table.
