Ë A 0.1-s standby time is not necessary to send the DTMS command and the SYS command after reset

clearance. To ensure system stability after turning on the power, send the DTMS command and the SYS

command after SENSE is set to "H".

NoteÊ£ To obtain the waveform shown in the above timing chart, the MLD pulse width should be 10 Âµs or

less. If it is more than the value, SENSE clear ("H" Ë "L") by the SYS command in the above

timing may not be performed.
