■ HANDLING DEVICES
1. Preventing Latchup
In CMOS ICs, applying voltage higher than VCC or lower than VSS to input/output pin or applying voltage over
rating across VCC and VSS may cause latchup.
This phenomenon rapidly increases the power supply current, which may result in thermal breakdown of the
device. Make sure to prevent the voltage from exceeding the maximum rating.
2. Treatment of Pins
•Treatment of unused pins
Unused pins left open may cause malfunctions. Make sure to connect them to pull-up or pull-down resistors.
•Handling the output pins
Connecting an output pin to the power supply, to another output pin, or to a large-capacitance load may cause
a large current to flow. Since letting it flow for an extended period of time degrades the device, be careful in
using the device not to exceed the maximum rating.
•Power supply pins
When there are several VCC and VSS pins, each of them is equipotentially connected to its counterpart inside of
the device, minimizing the risk of malfunctions such as latch up. To further reduce the risk of malfunctions, to
prevent EMI radiation, to prevent strobe signal malfunction resulting from creeping-up of ground level and to
observe the total output current standard, connect all VCC and VSS pins to the power supply or GND.
It is preferred to connect VCC and VSS of MB91107 to power supply with minimal impedance possible.
It is also recommended to connect a ceramic capacitor as a bypass capacitor of about 0.1 µF between VCC and
VSS at a position as close as possible to MB91107.
•Mode setting pins (MD0 to MD2)
Connect mode setting pins (MD0 to MD2) directly to VCC or VSS.
Arrange each mode setting pin and VCC or VSS patterns on the printed circuit board as close as possible and
make the impedance between them minimal to prevent mistaken entrance to the test mode caused by noises.
•Crystal oscillator circuit
Noises around X0 and X1 pins may cause malfunctions of MB91101. In designing the PC board, layout X0, X1
and crystal oscillator (or ceramic oscillator) and bypass capacitor for grounding as close as possible.
It is strongly recommended to design PC board so that X1 and X0 pins are surrounded by grounding area for
stable operation.
3. Notes on Use
•External reset input
The RST pin requires "L" level input for at least five machine cycles before the the internal circuitry can be
completely reset.
•External clock
To use an external clock, in principle, supply the X0 and X1 pins with a clock signal opposite in phase to the X0.
To use the STOP mode (oscillation stop mode) along with the external clock, in which the X1 pin stops with "H"
output, you should insert an external resistor of about 1 kilohm to prevent a collision between outputs.
Given the next page is an example of using an external clock.

Note: To use the STOP mode (oscillation stop mode), insert a resistor to the X1 pin.
4. Notes on Internal DC-DC Regulator
• Since this product contains a regulator, be sure to supply current at 3.3 V to the VCC pin and insert a bypass
capacitor of about 0.1 µF to the C pin for the regulator.
• The A/D converter requires a 3.3-V power supply separately.

• Notes on using the STOP mode
The regulator built in this product stops in the STOP mode. If the regulator stops due to a malfunction caused
by noise or a fault in the power supply during normal operation, the internal 2.5-V power supply may go below
the lower limit of the guaranteed operating voltage range. When using the STOP mode with the internal regulator,
therefore, be sure to supply an auxiliary external power to prevent the 3.3-V power supply from coming down.
Even in that case, the internal regulator can be restarted by input of a reset signal (To restart the regulator, keep
the reset pin at the L level for at least the oscillation settling time).

5. Turning on the Power Supply
•RST pin
When turning on the power supply, never fail to start from setting the RST pin to “L” level. And after the power
supply voltage goes to VCC level, at least after ensuring the time for 5 machine cycles, then set to “H” level.
•Pin Condition at Turning on the Power Supply
The pin condition at turning on the power supply is unstable. The circuit starts being initialized after turning on
the power supply and then starting oscillation and then the operation of the internal regulator becomes stable.
So it takes about 42 ms for the pin to be initialized from the oscillation starting at the source oscillation 12.5 MHz.
Take care that the pin condition may be output condition at initial unstable condition.
(With the MB91107, however, initalization can be achieved in less than about 42 ms after turning on the internal
power supply by maintaining the RST pin at "L" level.)
•Source Oscillation Input at Turning on the Power Supply
At turning on the power supply, never fail to input the clock before cancellation of the oscillation stabilizing waiting.
•Hardware Stand-by at Turning on the Power Supply
When turning on the power supply with the HST pin being set to “L” level, the hardware doesn’t stand by. However
the HST pin becomes available after the reset cancellation, the HST pin must once be back to “H” level.
•Power on Reset
Make sure to make power on reset at turning on the power supply or returning on the power supply when the
power supply voltage is below the warranty range for normal operation.

■ PERIPHERAL RESOURCES
1. I/O Ports
There are 2 types of I/O port register structure; PDR (port data register) and DDR (data direction register) .
• For input (DDR = “0”) setting;
PDR reading operation: reads level of corresponding external pin.
PDR writing operation: writes set value to PDR.
• For output (DDR = “1”) setting;
PDR reading operation: reads PDR value.
PDR writing operation: outputs PDR value to corresponding external pin.

5. PWM Timer
The PWM timer can output high accurate PWM waves efficiently.
MB91101 has inner 4-channel PWM timers, and has the following features.
• Each channel consists of a 16-bit down counter, a 16-bit data resister with a buffer for cycle setting, a 16-bit
compare resister with a buffer for duty setting, and a pin controller.
• The count clock of a 16-bit down counter can be selected from the following four inner clocks.
• Inner clock φ, φ/4, φ/16, φ/64
• The counter value can be initialized “FFFFH” by the resetting or the counter borrow.
• PWM output (each channel)
• Resister description
Cycle setting register: Reload data register with a buffer
Duty factor setting register: Compare register with a buffer
Transfer from the buffers uses the counter borrow method.
• Pin control outline
Set to ’1’ at a duty factor match. (Preferential)
Set to ’0’ at a counter borrow.
The output value fixed mode is available, which makes all ’L’ (or ’H’) output easy.
The polarity can also be specified.
• Interrupt requests can be generated by selected a combination of events:
This timer is activated.
A counter borrow is generated (cycle match).
A duty factor match is generated.
A counter borrow is generated (cycle match) or a duty factor match is generated.
DMA transfer can be invoked by the above interrupt request.
• Simultaneous activation of multiple channels of the PWM timer can be set by software or by using another
interval timer. Restarting the PWM timer during operation can also be set.

•Notes
1) Sudden change in supply voltage during operation may initiate a power-on sequence. To change supply voltage during operation, it is recommended to smoothly raise the voltage to avoid rapid fluctuations in the supply
voltage.
VCC
Not less than 3 V
A voltage rising rate of 50 mV/
ms or less is recommended.

2) Set RST pin to “L” level when turning on the device, at least the tRSTL duration after the supply voltage reaches
VCC is necessary before turning the RST to “H” level.
VCC

3) If the supply voltage goes below the lower limit of the guaranteed operating voltage range, be sure to restart
the power supply from the VSS level. This is because an internal power-on reset must be generated to restart
operation without allowing the internal circuit to run out of control.
The guaranteed operating voltage range of MB91107 is from 3.0 to 3.6 V.
