1.
Current which flows in the on-chip pull-up resistor is not included.
2.
The oscillation stabilization wait time is the time during which the CPU operation is stopped to prevent
unstable operation at the oscillation start.
3.
Depends on the basic interval timer mode register (BTM) setting (table below).
