89 / 120 page  MB90330A Series 89 (Continued) *6 : • Applicable to pins: P00 to P07, P10 to P17, P20 to P27, P30 to P37, P40 to P47, P50 to P57, P70 to P77, P80 to P87, P90 to P95, PB5, PB6 • Use within recommended operating conditions. • Use at DC voltage (current) • The +B signal should always be applied a limiting resistance placed between the +B signal and the microcontroller. • The value of the limiting resistance should be set so that when the +B signal is applied the input current to the microcontroller pin does not exceed rated values, either instantaneously or for prolonged periods. • 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 VCC pin, and this may affect other devices. • Note that if a +B signal is input when the microcontroller power supply 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 P60 to P67, P96, PA0 to PA7, PB0 to PB4, DVP, DVM, HVP, HVM, UTEST, HCON • Sample recommended circuits: *7 : A peak value of an applicable one pin is specified as a maximum output current. *8 : The average output current specifies the mean value of the current flowing in the relevant single pin during a period of 100 ms. *9 : The average total output current specifies the mean value of the currents flowing in all of the relevant pins during a period of 100 ms. 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.
