In the V850ES/JJ3, the communication mode is selected by inputting pulses (12 pulses max.) to the FLMD0 pin after
The following shows the relationship between the number of pulses and the communication mode.
Note The number of clocks is as follows depending on the communication mode.

When UARTA0 is selected, the receive clock is calculated based on the reset command sent
from the dedicated flash programmer after receiving the FLMD0 pulse.
