167 / 179 page  167/179 ST92141 - ELECTRICAL CHARACTERISTICS SPI TIMING TABLE (VDD = 5V ± 10%, TA = –40°C to +85°C, CLoad = 50pF, fINTCLK = 25MHz, unless otherwise specified) Note: Measurement points are taken with reference to VIH-VIH / VOH-VOH for positive pulse and VIL-VIL / VOL-VOL for negative pulse (1) Values guaranteed by design. Legend: Tck = INTCLK period = OSCIN period when OSCIN is not divided by 2; 2 x OSCIN period when OSCIN is divided by 2; OSCIN period x PLL factor when the PLL is enabled.
