9. Details of the C pin handling for MB89530H series
MB89530H series contains the following products and the operating characteristics vary with whether they
contain the internal stepdown circuit.

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 voltage step-down circuit.
The operating sequences after the power-on reset with the different models will be described below.

*: With the MB89P538, you can select the voltage step-down circuit to be included or not by introducing the
C pin handling.
Note: 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.
