*1: Input levels are fixed to prevent leakage by leaving inputs open.
*2: Pin state specification bit (SPL) in the standby control register (STBC)
*3: Operates as a port depending on the external bus pin control register (BCTR) settings.
*4: Pins with a pull-up resistor (optional) go to the pull-up state.
*5: Outputs the write value to the standby control register (STBC).
*6: Outputs the upper address of the standby control register (STBC).
Hi-z: High impedance
Hold: The pin set as output, holds its state (level) immediately before changing to each mode.
