MB90340E Series
26
VCC ripple variations (peak-to-peak value) at commercial frequencies (50 Hz/60 Hz) fall below 10
% of the
standard VCC supply voltage
The coefficient of fluctuation does not exceed 0.1 V/ms at instantaneous power switching.
14. 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.
15. Port 0 to Port 3 Output During Power-on (External-bus Mode)
As shown below, when the power is turned on in External-Bus mode, there is a possibility that output signal of
Port 0 to Port 3 might be unstable irrespective of the reset input.
16. Notes on Using the CAN Function
To use the CAN function, please set the DIRECT bit of the CAN Direct Mode Register (CDMR) to 1.
If the DIRECT bit is set to ’0’ (initial value), wait states will be performed when accessing CAN registers.
Note : Please refer to the Hardware Manual of the MB90340E series for detail of CAN Direct Mode Register.
17. Flash Security Function (except for MB90F346E)
A 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.
Refer to following table for the address of the security bit.
