14.3 SPI-bus timing characteristics

Table 55. SPI-bus timing characteristics

VDD1, VDD2, VDD3 = 2.5 V to 5.5 V; VSS1 = 0 V; VLCD = 4.0 V to 12.0 V; Tamb = 40 C to +105 C; unless otherwise specified.

All timing values are valid within the operating supply voltage and ambient temperature range and are referenced to VIL and

VIH with an input voltage swing of VSS1 to VDD1.
