11. Notes on Energization
To prevent the internal regulator circuit from malfunctioning, set the voltage rise time during energization at 50
or more
s (0.2 V to 2.7 V)
12. Stabilization of power supply voltage
A sudden change in the supply voltage may cause the device to malfunction even within the specified VCC supply
voltage operating range. Therefore, the VCC supply voltage should be stabilized.
For reference, the supply voltage should be controlled so that VCC ripple variations (peak-to-peak value) at
commercial frequencies (50 Hz to 60 Hz) fall below 10
% of the standard VCC supply voltage and the coefficient
of fluctuation does not exceed 0.1 V/ms at instantaneous power switching.
13. Initialization
In the device, there are internal registers which are initialized only by a power-on reset. To initialize these registers,
turn on the power again.
14. Port 0 to port 3 output during Power-on (External-bus mode)
As shown below, when power is turned on in External-Bus mode, in spite of reset inpu, there is a possibility that
output signal of Port 0 to Port 3 might be unstable.
15. Notes on using CAN Function
To use CAN function, please set ’1’ to DIRECT bit of CAN Direct Mode Register (CDMR).
If DIRECT bit is set to ’0’ (initial value), wait states will be performed when accessing CAN registers.
Please refer to Hardware Manual of MB90340 series for detail of CAN Direct Mode Register.
16. Flash security Function (except for MB90F346A)
The security bit is located in the area of the flash memory.
If protection code 01H is written in the security bit, the flash memory is in the protected state by security.
Therefore please do not write 01H in this address if you do not use the security function.
Please refer to following table for the address of the security bit.
