2 ms is the nominal time required for the 4x PLL to lock.
72 ms is the nominal power-up timer delay, if implemented.
1.5 µs is the recovery time from Sleep. There is no recovery time from oscillator switch.
When the wake-up is due to an interrupt and the GIEH or GIEL bits are set, the PC is loaded with the
interrupt vector (0008h or 0018h).
