7.5.2 Manual Power ON Applied to the DELAY/M_DRV Pin
If VDD is applied to the DELAY/M_DRV pin after start-up is completed, the TPL5111 recognizes this as a manual Power ON condition. In this case REXT is not re-read. If the manual Power ON is asserted during the POR or during the REXT reading procedure, the reading procedure is aborted and is restarted as soon as the manual Power ON switch is released. A pulse on the DELAY/M_DRV pin is recognized as a valid manual Power ON only if it lasts at least 20 ms (observation time is 30 ms). If DRVn is already HIGH the manual Power ON is ignored. The manual Power ON may be implemented using a switch (momentary mechanical action).
