Table 28-8. Relationship Between FLMD0 and FLMD1 Pins and Operation Mode When Reset Is Released
The following shows the pins used by each serial interface.
When connecting a dedicated flash programmer to a serial interface pin that is connected to another device
on-board, care should be taken to avoid conflict of signals and malfunction of the other device.
(a) Conflict of signals
When the dedicated flash programmer (output) is connected to a serial interface pin (input) that is
connected to another device (output), a conflict of signals occurs. To avoid the conflict of signals, isolate
the connection to the other device or set the other device to the output high-impedance status.

In the flash memory programming mode, the signal that the dedicated flash
programmer sends out conflicts with signals another device outputs.
Therefore, isolate the signals on the other device side.
