Note: You can only use one interface exclusively. It is not allowed to use e.g. the parallel and serial host interface at the same time.
Note 1): The “LBU_READY_OUT” is designed to connect only to one microcontroller. If you want to connect additional devices you must
add circuitry to realize the high-impedance state.
Note 2): If your processor does not have a READY Input, you can choose a wait time of 260 ns during each transfer cycle.
Note 3): As soon as the signal HOST_SFRN_IN is set to “1”, no more data is received on the RxD interface. Setting the signal is not allowed
during an ongoing transfer.
