(4) SPI0_ENA is driven low after the transmission completes if the SPIINT0.ENABLE_HIGHZ bit is programmed to 0. Otherwise it is tri-stated. If tri-stated, an external pullup resistor should
be used to provide a valid level to the master. This option is useful when tying several SPI slave devices to a single master.
