Section 5 Restriction on the Interface
The following restriction applies to the interface when pins PF7, PF6, and PF5 of the MCU are
selected as CS-output pins by the emulator, to which the user system interface board is connected.
Jumper pins (SW1 to SW3) are used to switch the functions of pins PF7, PF6, and PF5 between
port and CS-output functions. While these pins are in use as CS-output pins, the functions of PF7,
PF6, and PF5 are disabled.
