Notes 1.

This pin can be switched by software between function-pin and output-port uses.

The state at the previous Fullspeed mode is retained.

Normal operations are performed.

Be sure to set the BSC bit (DI) of the HSPINT register (0x0C00 0020) to 1 during initialization.

After RTC reset is canceled, this signal functions as an output port.

Remark

0: outputs low level, 1: outputs high level, Hi-Z: high-impedance
