*1: In BURST(Mode for sampling data at all clock edges), only the monitor mode is supported. I2C and SPI do not have the BERT function.
*2: Applied in the half duplex. In the full duplex 2.15Mbps at Max.
*3: Applied in the half duplex. In the full duplex 6Mbps at Max.
*4: MAX 20Mbps(Monitor) or 4Mbps(Simulation), when the continuous transfer speed is within 1K bytes.
*5: Applied in the monitor mode. In the simulation mode, the speed is up to 12Mbps.
*6: Set from the analyzer. CMOS outputting is recommended on simulation of which speed is more than 2Mbps.
*7: Applied when the current is 4 mA.
