*1 : It is setting of Jumper switch SI when Emulation Pod (MB2147) is used.
Please refer to the Emulator hardware manual about details.
*2 : Oscillation time of the oscillator is the time that the amplitude reaches 90%.
*3 : Data is based on reliability tests during process qualification (the value for TA = + 85 °C is calculated via
the Arrenhius formula from data of accelerated measurements at elevated temperature) .
