SPI
Module WE866 is considered as a slave when it is interfaced with a Host which acts as
master. In addition to the standard SPI lines (MOSI, MISO, CLK, CS) it can be used also
HOST_INT line. WE866 can interrupt the host using HOST_INT line to initiate the data
transfer over the interface. The SPI interface can work up to a speed of 20MHz.
