Power Down | 6 CLK + OSC start-up |
In addition to the normal wake-up time it is possible to make the device wait until the BOD is ready before executing code. This is done by writing 0x3 to the BOD Operation Mode in Active and Idle bits (ACTIVE) in the BOD Configuration fuse (FUSE.BODCFG). If the BOD is ready before the normal wake-up time, the net wake-up time will be the same. If the BOD takes longer than the normal wake-up time, the wake-up time will be extended until the BOD is ready. This is ensures correct supply voltage whenever code is executed.
