The selectable transfer speeds shown in
following equations:
If BR_T0[2:0] = 0:
If BR_T0[2:0] > 0:
Remark: Transfer speeds above 1228.8 kBd are not supported.
Table 12.
Remark: The LSB for data and address bytes must be sent first. No parity bit is used
during transmission.
To read data using the UART interface, the flow shown in
byte sent defines both the mode and the address.
