8.6 USB to SPI (Master) Converter
Figure 8.6 Application Example showing USB to SPI (Master) Converter
This example shows the CNFGx pins set for mode 101 – SPI (Master).
The FT311D SPI Master controls the slave select line and the clock to the external SPI slave.
SPI_M_MOSI is the FT311D data output line which may be Most or Least Significant Bit first.
SPI_M_MISO is the FT311D data input line which may be Most or Least Significant Bit first.
Example SPI Slave devices include memory, RTC, and codec devices.
The unused pins may be left unterminated.
Power to the USB port is enabled by the VBUSCTRL# signal
