Notes1. Maintains the state of the previous Fullspeed mode.
2. The state depends on the MEMCFG_REG register setting.
3. The state depends on the GPHIBSTH/GPHIBSTL register setting.
4. The input level is sampled to determine the MIPS16 instruction mode.
Remark 0: low level, 1: high level, Hi-Z: high impedance
