• Operation in stop mode and watch mode
• If the pin state setting bit in the standby control register (STBC:SPL) is set to “1” and the device transits to stop
mode or watch mode, the pin is compulsorily made to enter the high impedance state regardless of the DDRB reg-
ister value. The input of that pin is locked to “L” level and blocked in order to prevent leaks due to input open.
• If the pin state setting bit is “0”, the state of the port I/O or that of the peripheral function I/O remains unchanged
and the output level is maintained.
