Asynchronous/Synchronous Serial Interface (ASC)
Note: In synchronous operating mode, the direction of the RxD pin is not automatically
set by the ASC modules; it must be switched by software via the corresponding bit
in register DP3, depending on the selected mode (receive or transmit data).
Note: To select RxDA1 as alternate output function for P3.1, it is sufficient to set bit 1 of
register ALTSEL0P3, the corresponding bit in register ALTSEL1P3 is “don’t care”.
