Character code bits 0 to 3 correspond to CGRAM address bits 3 to 6.
CGRAM address bits 0 to 2 designate the character pattern line position. The 8th line is the cursor position and display is performed by logical OR with
the cursor. Data in the 8th position will appear in the cursor position.
Character pattern column positions correspond to CGRAM data bits 0 to 4, as shown in Fig.6.
As shown in Figs 6 and 7, CGRAM character patterns are selected when character code bits 4 to 7 are all logic 0. CGRAM data = logic 1 corresponds
to selection for display.
Only bits 0 to 5 of the CGRAM address are set by the ‘set CGRAM address’ command. Bit 6 can be set using the ‘set DDRAM address’ command in
the valid address range or by using the auto-increment feature during CGRAM write. All bits 0 to 6 can be read using the ‘read busy flag and address
counter’ command.
