28.4.4 Selection of communication mode
after switching to the flash memory programming mode. The FLMD0 pulse is generated by the dedicated flash
programmer.
In the V850ES/JG3-L, the communication mode is selected by inputting pulses (12 pulses max.) to the FLMD0 pin
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.
