*1 : The parameter is based on AV_SS = V_SS = 0.0 V.
*2 : ` Applicable to pins : P00 to P07, P10 to P17, P20 to P27, P30 to P37, P50 to P52, P80 to P82
` Use within recommended operating conditions.
` Use at DC voltage (current) .
` The +B signal should always be applied with 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 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 result.
` 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.

The MB89498 series has been developed as a general-purpose version of the F2MC*-8L family consisting of proprietary 8-bit single-chip microcontrollers.

In addition to a compact instruction set, the general-purpose, single-chip microcontroller contains a variety of peripheral functions such as 21-bit timebase timer, watch prescaler, PWM timer, 8/16-bit timer/counter, remote receiver circuit, LCD controller/driver, external interrupt 0 (edge) , external interrupt 1 (level) , 10-bit A/D converter, UART/SIO, SIO, I2C and watchdog timer reset.

The MB89498 series is designed suitable for compact disc/radio receiver controller as well as in a wide range of applications for consumer product.
