Note that when the microcontroller drive current is low, such as in the power saving modes, the
+
B input
potential may pass through the protective diode and increase the potential at the V
CC
pin, and this may affect
other devices.
Note that if a
+
B signal is input when the microcontroller current is off (not fixed at 0 V) , the power supply
is provided from the pins, so that incomplete operation may result.
Note that if the
+
B input is applied during power-on, the power supply is provided from the pins and the
resulting supply voltage may not be sufficient to operate the power-on reset.
Care must be taken not to leave the
+
B input pin open.
Note that analog system input/output pins other than the A/D input pins (LCD drive pins, comparator input
pins, etc.) cannot accept
+
B signal input.
Sample recommended circuits:
Input/Output Equivalent circuits
*8 : P24 to P27, P30 to P37, P40 to P42, P70 to P74, P76, P77 pins can be used as 5 V I/F pin on applied 5 V

P76 and P77 is N-ch open drain pin.
*9 : As for P76 and P77 (N-ch open drain pin) , even if using at 3 V simplicity (V

WARNING:
Semiconductor devices can be permanently damaged by application of stress (voltage, current,
temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.
