* Refer to the Timing Waveform in P.12, where n=0, 1, 2, 3.
**In timing of “Read Configuration” and “Read Error Status Code”, the next DCLK rising edge should be tPD2 after the
falling edge of LE.
***Users have to leave more time than the maximum error detection time for the error detection.
****With uniform output current.
