interesting experiment, but after reading the datasheet I don't think 1x mode is usable in T200 in general. It assumes that the clock and data are phase aligned, whereas in 16x mode the UART counts 8 pulses to find middle of the eye.
However 38400 should be doable in 16x mode. On Sat, Jun 2, 2018 at 5:41 PM, John R.
