27.8.2 Selection of communication mode
FLMD0 pin after switching to the flash memory programming mode. The FLMD0 pulse is generated by the flash
memory programmer.
In the V850E/IF3 and V850E/IG3, the communication mode is selected by inputting pulses (11 pulses max.) to the
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 flash memory programmer after receiving the FLMD0 pulse.
