7.3.9.1 Pushbutton Wake or Short Button Press Functions

There are two programmable wake or short button press timers, Wake1 and Wake2. There are no specific actions taken by the twake1 or twake2 durations other than issuing an interrupt and updating the MR_WAKE registers. For a wake from ship mode event , the push button has to be low for tshipwake before it can turn ON the SYS rail. This only applies to ship mode; a button press that pulls the TS/MR pin low for a duration tshipwake will not turn on the SYS rail when the device is in shutdown mode

In the case where a valid VIN (VIN > VUVLO) is connected prior to tshipwake timer expiring, the device will exit the shipmode immediately regardless of the TS/MR or wake timer state. Refer to Section 7.5 for more details.

The EN_PUSH bit will enable the button checking event through the periodic wake up of the current source on the TSMR pin. The timing will be similar to when in shipmode. When this bit is enabled all button events such as Wake1, Wake2 and MR_LPRESS events are valid. When this function is disabled, the button events are ignored. When the adapter is present and charging is actively in progress, this bit status is ignored as the current source is ON/ OFF when the NTC is being checked.
