10. Handling reset pin
Reset pin must be inputted external reset.
11. Up/down conversion circuit stabilization waiting time
MB89210 series contains the following products and the operating characteristics vary with whether they contain
the internal stepdown circuit.
* : The minimum operating voltage varies with the operating frequency, the function and the connected ICE.
The same built-in resources are used for the above product types; operating sequences after the power-on reset
are different depending on whether they have the internal voltages step-down circuit.
The operating sequences after the power-on reset with the different models will be described below.
As described above, CPU starts at delayed time with the product having the internal voltage step-down circuit
compared with the product not having the internal voltage step-down circuit. This is because the time should be
allowed for the stabilization time for voltage step-down circuit for normal operation.
Note : As the period of the oscillation is unstable immediately after oscillation starts, the listed oscillation stabilization
delay times are guides only.
12. Treatment of analog input
The analog input also serves as a general-purpose input/output port. The A/D enable register is initialized at a
reset. When the intermediate-level signal is input in port input mode (ADEN:ADEx = 0), an input leakage current
flows to the gate. Set the corresponding pin to an analog input.
