Character code bits 0 to 3 correspond to CGRAM address bits 3 to 6.
CGRAM address bits 0 to 2 designate character pattern line position. The 8
th
line is the cursor position and display is performed by logical OR with the
cursor. Data in the 8
th
line will appear in the cursor position.
Character pattern column positions correspond to CGRAM data bits 0 to 4; bit 4 being at the left end, as shown in the figure.
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’ instruction. Bit 6 can be set using the ‘Set DDRAM address’ instruction 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’ instruction.
