The Oscillator Start-up Timer (T

Figure 2 shows the start-up of the crystal after the
event that causes the device to wake up from sleep
mode (as specified in device data sheet). The start-
up time (T
The events that wake-up the device from sleep are:
• An interrupt
• A WDT overflow (wake-up)
• A Brown-out Reset
• A MCLR reset
In applications where time based measurements are
started immediately after wake-up from sleep, the
suggested work around should be implemented.
