Note: Function 1 can be used when the AUD pins of the device are not connected to the

emulator.

The AUD pins are multiplexed with other pins. When the AUD function is used by the

SH7286, SH7285, and SH7243 E200F emulator, AUD pins are used regardless of the settings

of the pin function controller (PFC).

Note that the AUD function can be used regardless of the above AUD pin settings in EV-chip unit

debugging mode.

The WDT does not operate during a break.
