The '754C can decode positive pulses on Rx. The timing is different, but the variation is invisible to the UART.

The decoder, which works from the falling edge, now recognizes a zero on the trailing edge of the pulse rather

than on the leading edge. As long as the pulse width is fairly constant, as defined by the specification, the trailing

edges should also be 16 clock cycles apart and data can readily be decoded. The zero appears on Int_Rx after

the pulse rather than at the start of it.
