Notes 1. When initializing, always set BSC bit to 1 in the HSPINT register (0x0C00 0020).

2. The state of the previous Full-speed Mode is maintained.

3. Normal operation proceeds.

4. After the RTC reset is released, this functions as an output port.

5. Specify the input data level using a high-resistance pull up or pull down resistor.

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