In this mode, an external SoC directly communicates with the serial controller through the
SPI interface: SPI_MOSI, SPI_MISO, SPI_CLK, SPI_CS. The serial controller has a
built-in SPI slave function. An external SPI master can access the internal registers of the
ISP1109 through the SPI interface. The maximum SPI clock rate is 26 MHz.
