> Function | Signal name | IO | Signal form and level | Comment
> SPI Serial Peripheral Interface | I2CCLK_SPICLK | O | R O ≈ 33Ω VOLmax = 0.25V at I = 2mA VOHmin = 2.50V at I = -0.5mA VOHmax = 3.05V Fmax = 6.5MHz (possible) 1.083 MHz (recommended) V ILmax = 0.8V VIHmin = 2.0V VIHmax = 3.05V | If the Serial Peripheral Interface is active the I2C interface is not available. If lines are unused keep pins open.
