First and last cell number for each preprogrammed pattern are
Sequence = Start – Address+W – 0x00 – Data[7:0] – Stop
If Data[Bit_Position] = 0 then Data[Bit_Position] = 1
If Data[Bit_Position] = 1 then Data[Bit_Position] = 0
If Pattern_Number ≠ 4 then Increase Pattern_Number
If Pattern_Number = 4 then Pattern_Number = 1
Display Pattern_Number using LD13 to LD20
Read each I
[Pattern_Number] and Max[Pattern_Number]
Send data read from EEPROM
Loop between 3) and 4) until S5 pushed again
Program P89LPC932 with the programmed byte
LD13 to LD20 display the programmed byte
LD[Bit_Position+1] = Data[Bit_Position]
If Bit_Position = 0, then Bit_Position = 7
If Bit_Position = 7, then Bit_Position = 0
memorized by the P89LV51RD2
Scan the PCF85116 EEPROM
Min and Max for each pattern
Else Decrement Bit_Position

Else Increment Bit_Position
