3.5.7 Wake-Up Operation
There is a wake-up key on the LCD EV-Board, which uses external interrupt to wake up
system from sleep mode.
When system enters sleep mode, no operation can be made except the wake-up key.
The following operation describes the wake-up process.
9
When the timer is the same as standby setting time, system will enter sleep mode.

3.5.8 Reset Operation
There is a reset key to be used when user wants to reset system. In normal condition, the
reset pin is connected to VCC. While reset key pressed, it is connected to GND.
3.5.9 Factory Operation
In EEPROM normal mode, press Send key and then press Wakeup key, and EEPROM
value will be initialized to its sub-address value.
3.5.10 Test Pin
For every pin of MB95F310, there is a test pin connected to it.
3.5.11 Battery Usage
The supply power is 3.3V for MCU EEPROM and MAX232. The LCD EV-Board uses power
chip AMS1117-3.3 to transfer input power from 5V to 3.3V, so the maximum number of
battery supply cannot be more than four cells (1.5V each cell).

function which transfers the C file of ADC when user wants to use ADC, the C file of I2C
when the user wants to use I2C, and the C file of RTC when the user wants to use RTC.
ADC0_Init();
// initialize ADC
UART_init();
// initialize UART
EXT_Init();
// initialize Interrupt
Init_LCD();
// initialize LCD
TBT_Init();
// initialize Timebase timer
Init_EEProm();
// initialize EEPROM
while(1)
{
ADCTempSwitKey();
// Judge key value
Process_Control();
// transfer every
library
LCD_LigON_NUM(0,2);
// display LCD
}

5 Development Platform Quick Start
5.1
Tools Setup Sequence
Start the debugging system in the following sequence:
9
Connect a BGMA to the PC with a USB cable, confirm whether the LED on the BGMA is
green;
9
Connect an EV-board to BGMA IDC10 socket;
9
Select the EV-board power supply and turn on the EV-board, confirm whether the LED
on the BGMA is orange and the Power LED on the EV-board is on.
5.2
Open Project and Start Debug
Users can start a debug from a PC software SOFTUNE workbench in the following
sequence. Take SIMULATE LCD EVBOARD project as an example.
9
Start the SOFTUNE by selecting Programs> SOFTUNE V3> FFMC-8L Family
SOFTUNE Workbench from Start Menu;
9
Click Open workspace from File Menu in SOFTUNE;
9
Select SIMULATE LCD EVBOARD.wsp in Open Space window;
9
Click Start debug from Debug Menu.
If the entire procedure goes right, a debug will start normally.
5.3
Operation Precautions
9
All pins of MB95F310 Series MCU are connected to Testing Pin on the EV-board. If user
wants to test the performance of a single pin, please connect it to the test pin.
9
Note: before connecting with BGMA, do not power on system.
9
It’s recommended that only one power supply is used as a power module input at a time.
