change then during operation.
The V850E/IF3 and V850E/IG3 have the following operating modes. Mode specification is carried out using the
(1) Normal operation mode
(2) Flash memory programming mode
The operating mode is specified according to the status (input level) of the FLMD0 and FLMD1 pins.
In the normal operating mode, input a low level to the FLMD0 pin after reset.
When the flash memory programmer is connected, a high level is input to the FLMD0 pin by the flash memory
Other than in the self-programming mode, fix the specifications of these pins in the application system, and do not

In this mode, execution branches to the reset entry address in the internal ROM and instruction processing is
started when system reset is released.
If this mode is specified, a program can be written to the internal flash memory by the flash memory
programmer.
