ASC asynchronous baud rates by reload value and deviation errors (f
The deviation errors given in the
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 ST10F273Z4. Half-duplex communication up to 8M Baud (at 40 MHz of
