2,A. CGRAM data write
(CGRAM writes character pattern data.)
CGRAM (Character Generator RAM) has a 4-bit address to store 5x 7 dot matrix character patterns.
A character pattern stored in CGRAM can be displayed by specifying the character code
(address) by
DCROM.
The address of CGRAM is assigned to 00H to 0FH. (All the other addresses are the CGROM addresses.)
(The CGRAM can store 16 types of character patterns.)
[Command format]
To specify character pattern data continuously to the next address, specify only character pattern data as follows.
The addresses of CGRAM are automatically incremented. Specification of an address is unnecessary.
The 2nd to 6th byte (character pattern data) are regarded as one data item, so 200 ns is sufficient for tDOFF time
between bytes.
