Legend
H:
High
L:
Low
T:
High-impedance state
keep: Input pins are in the high-impedance state; output pins maintain their previous state.
DDR: Data direction register bit
Notes: 1. The bus cannot be released in mode 7.
2. Output is low only for reset by WDT overflow.
3. During direct power supply, oscillation damping time is “H” or “T”.
4. During direct power supply, oscillation damping time differs between “H”, “L” and “T”.
