Bit0 (LCD_M):LCD_M decides the methods, including duty, bias, and frame frequency.
Bit1~Bit2 (LCD_C#):LCD_C# decides the LCD display enable or blanking.
change the display duty must set the “LCD_C2,LCD_C1” to “00”.
Bit3 (/WURING, RING Wake Up Enable): used to enable the wake-up function of /RINGTIME input pin.
(1/0=enable/disable)
Bit4 (/WUP9L, PORT9 low nibble Wake Up Enable): used to enable the wake-up function of low nibble in
PORT9.(1/0=enable/disable)
Bit5 (/WUP9H, PORT9 high nibble Wake Up Enable): used to enable the wake-up function of high nibble
in PORT9.(1/0=enable/disable)
Bit6 (/WDTE,Watch Dog Timer Enable)
Control bit used to enable Watchdog timer.
(1/0=enable/disable)
The relation between Bit3 to Bit6 can see the diagram 9.
