5.2 Initial Reset Sequence
CPU startup waits for the oscillation stabilization standby time (1024/fosc3 seconds*) to expire after resetting is
cancelled via the #RESET pin at power-on. Figure 5.2.1 illustrates the sequence of operations after canceling the
initial reset. The CPU starts up in sync with the OSC3 clock after the reset is canceled.
*fosc3: OSC3 clock frequency
Note: The oscillation stabilization standby time does not include the oscillation start time. The time
may be longer than that shown between power-on or SLEEP cancellation and command ex-
ecution.
