Figure 4.11: FT1248 1-bit Mode Protocol (READ)
When SS_n is inactive the write buffer and read buffer status is reflected on the MIOSIO[0] and MISO
signals respectively. When the master wishes to initiate a data transfer, SS_n becomes active. As soon as
SS_n becomes active the SPI slave immediately stops driving the MIOSIO[0] signal and SPI master is not
allowed to begin driving the MIOSIO[0] signal until the first clock edge, this ensures that bus contention
is avoided.
