Note:
The deviation errors given in the Table 52 and Table 53 are rounded. To avoid deviation
errors use a Baud rate crystal (providing a multiple of the ASC0 sampling frequency).

ASCx in synchronous mode
In synchronous mode, data is transmitted or received synchronously to a shift clock which is
generated by the ST10F276. Half-duplex communication up to 8M Baud (at 40 MHz of fCPU)
is possible in this mode.
