3.3 Operating Modes
38
The V850ES/IE2 has the following operating modes.
(1) Normal operating mode
(2) Flash memory programming mode
(a) Operating mode specification
After the system has been released from the reset state, the pins related to the bus interface are set to the port
mode, execution branches to the reset entry address of the internal ROM, and instruction processing is
started.
When this mode is set, a program can be written to the internal flash memory by the flash memory
programmer.
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 programmer in the flash memory programming mode; however, in the self-programming mode,
input a high level via an external circuit.
Fix the specifications of these pins in the application system, and do not change then during operation.
