Datasheet - AS8515 To p Die Overview

7.12 Wake-up

When the device enters standby mode, it can be brought back to the normal mode. A dominant state on the BUS for duration of tWAKE (see Table

25) will result in the device wake-up which is termed as remote wake.

7.12.1 Remote Wake-up Event

In all low power modes of

Top die, low power BUS receiver is ON. If BUS is in dominant state for longer than tWAKE then, remote wake is

sensed on the BUS and REMOTE_WAKE_flag is set. Indication of wake-up is given to µC by setting a bit in interrupt register and giving interrupt

on INTN pin.
