10. Connection of unused pins of A/D converter if A/D converter is used
11. Notes on energization
12. Stabilization of power supply voltage
13. Initialization
14. Notes on using CAN function
Note : Please refer to Hardware Manual of MB90360 series for detail of CAN Direct Mode Register.
15. Flash security function
16. Correspondence with +105 °C or more
Connect unused pins of A/D converter to AV
To prevent the internal regulator circuit from malfunctioning, set the voltage rise time during energization at
50 µs or more (0.2 V to 2.7 V)
A sudden change in the power supply voltage may cause the device to malfunction even within the specified
V
lized.
For reference, the power supply voltage should be controlled so that V
at commercial frequencies (50 Hz to 60 Hz) fall below 10% of the standard V
coefficient of transient fluctuation does not exceed 0.1 V/ms at instantaneous power switching.
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.
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.
The security bit is located in the area of the flash memory.
