(Continued)
*1 : Pins become inputs and can be used to wakeup from STOP mode when the corresponding external interrupt
is enabled in ENIR and the pin is selected as an external interrupt input pin in EISSR.
*2 : Outputs go to Hi-Z at power on or while the INIT pin is at the “L” level starting from the falling edge on the INIT pin.
Input enabled
: This indicates that the input function is available in this state.
Input disconnect
: Disconnects the external input at the input gate immediately adjacent to the pin .
An "L" level is passed to internal circuits.
Output Hi-Z
: This makes the pin go to high-impedance by preventing the pin drive transistor from
driving.
Output is maintained
: Indicates that pins maintain the output level they had prior to changing to this mode.
In other words, the pin outputs the value from the internal peripheral if the internal
peripheral that uses the output is operating, and the pin maintains its output level if the
pin is set as a port.
Maintain previous state : Indicates that output pins maintain the output level they had prior to changing to this
mode, and input pins continue to operate.
