●

Nibble[1] in LCD_RAM3[4:6] bits: page0 COM1

●

Nibble[2] in LCD_RAM0[0:2] bits: page1 COM4

●

Nibble[3] in LCD_RAM3[4:6] bits: page1 COM5

●

Nibble[4] in LCD_RAM7[0:2] bits: page1 COM6

●

Nibble[5] in LCD_RAM10[4:6] bits: page1 COM7

Note:

All upper case letters and numbers are converted from ASCII characters to LCD_RAM
