(3) Serial interface pin
The following shows the pins used by each serial interface.
When connecting a dedicated flash memory 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 memory 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.

CSIB0 + HS
In the flash memory programming mode, the signal that the dedicated flash
memory programmer sends out conflicts with signals another device
outputs. Therefore, isolate the signals on the other device side.
