19.7.3 Selecting communication mode
In the
µ
PD78F0730, a communication mode is selected by inputting pulses (up to 11 pulses) to the FLMD0 pin
after the dedicated flash memory programming mode is entered. These FLMD0 pulses are generated by the flash
memory programmer.
The following table shows the relationship between the number of pulses and communication modes.

Caution When UART6 is selected, the receive clock is calculated based on the reset command sent from the
dedicated flash memory programmer after the FLMD0 pulse has been received.
