(2) When character pattern is 5 x 10 dots (see Table 3-2).
A method of writing character pattern into the CG RAM by the CPU:
Four bits of CG RAM address, bits 0-3, correspond to the line position of the character
pattern.
First, set increment or decrement with the CPU, and then input the address of the CG
RAM.
After this, write the character pattern code into the CG RAM, line by line from DB0-
DB7.
DB0 to DB7 correspond to CG RAM data, bits 0-7, in Table 3-2.
It is displayed when "H" is set as input data, while it is not displayed when "L" is set
as input data.
As the ADC is automatically incremented or decremented by 1 after the writing of
data to the CG RAM, it is not necessary to set the CG RAM address again.
The line, the CGRAM addresses 0-3 of which are "A" in hexadecimal notation, is the
cursor position. The CGRAM data is 0Red with the cursor at the cursor position and
displayed to LCD. For this reason, it is necessary to set all input data that become
cursor positions to "L".
When the CG RAM data, bits 0-4, and CG RAM addresses, bits 0-3, are "0" to "A", they
are displayed on the LCD as the display data. When the CG RAM data, bits of 5-7,
and CG RAM, bit data is 0-4 and CG RAM address data is "B" to "F", it is not output
to the LCD.
But in this case, CG RAM can be used as RAM and it can be written into/read out.
So, it can be used as the data RAM.
A method of displaying the CG RAM character pattern to the LCD:
The CG RAM is selected when 4-upper order bits of the character code are all "L".
As character code bits 0 and 3 are invalid, the display of "m" is selected by character
codes "00", "01", "08", and "09" (hex.) as in Table 3-2.
When the CG RAM character code is written to the DD RAM, the CG RAM character
pattern is displayed on the LCD display position corresponding to the DD RAM
address.
(DD RAM data bits 1 and 2 correspond to CG RAM address bits 4 and 5.)
