5. 1 Raising power supply voltage
The I
communication error. This function allows detection of a communication failure during data communication
between the microprocessor and E
recommended to perform an acknowledge check on the microprocessor side.
E
may cause a malfunction. For the power-on-clear circuit to operate normally, the following conditions must
be satisfied for raising the power supply voltage.
Raise the power supply voltage, starting at 0.2 V maximum, so that the voltage reaches the power supply
voltage to be used within the time defined by t
For example, when the power supply voltage to be used is 5.0 V, t
The power supply voltage must be raised within 200 ms.
