M = {(0.5 – 1/2N) – (D – 0.5)/N – (L – 0.5)F}
When D = 0.5 and F= 0
M = (0.5 –1/2

interface 1 or 2 to transmit in synchronous mode, make sure the ORER bit is cleared to 0.
Transmit operation will fail to start if the ORER bit is set to 1. The same is true in
simultaneous transmitting and receiving.
