Pin State in Standby Mode, Hold, and Reset

The states of the pins in the standby mode and in the hold and reset states are
described for each memory access mode.
Pin state in single chip mode
Table 6.7-1 "Pin states in single chip mode" lists the pin states in the single-chip mode.

*1: Same as in other ports when used in the output state. "Input enabled" means that input functions are
ready and require pull up/pull down or external input.
*2: The state output immediately before this mode was set is output as is. If it is input, input is disabled.
"Input disabled" means that operations of input gates located very close to the pins are enabled, but pin
states cannot be accepted in internal operations because internal circuits are not operating.
*3: "Input cutoff" means that operations of input gates located very close to the pins are disabled. "Output
Hi-Z" means that the pin-drive transistors are disabled and the pins are set to the high-impedance state.
