C0–7: Corresponds to the 2nd byte of the CGRAM data write
command.
C8–15: Corresponds to the 3rd byte of the CGRAM data write commnad.
*On CGROM
A CGROM (Character Generator ROM) has an 8-bit address to generate alphanumeric type matrix
character patterns.
It has a capacity of 240 x 16 bits and can store 240 types of character patterns.
