• CG/DD (CG RAM/DD RAM)
This bit indicates whether the address counter contents are CG RAM or DD RAM when
B1F = "L". It indicates that CG RAM data has been selected when CG/DD = "H" and that
DD RAM data has been selected when CG/DD = "L".
• I/D (Increment/Decrement)
This bit indicates which has been set in the entry mode set, increment or decrement, when
B1F = "L". It indicates that increment has been set when I/D = "H" and that decrement has
been set when I/D = "L".
• S (Shift)
This bit reads the shift condition in the entry mode when B1F = "L". It indicates that shift
is set when S = "H" and shift is disabled when S = "L".
• A/O (CG RAM ENABLE/CG ROM ENABLE)
This bit indicates which has been selected in the entry mode, CG ROM or CG RAM, when
BIF = "L".
It indicates the CG ROM selected state when A/O = "L" and CG RAM selected state when
A/O = "H".
• D (Display)
This bit indicates which has been set by display control instruction, LCD display ON or
OFF, when B1F = "L". It indicates that the display is on when D = "H" and the display is
off when D = "L".
• UD (Underline)
This is the bit to indicate the condition of underline or blinking on the underline, both of
which were set by display control instruction, when B1F = "L".
When UD = "H", either (or both of) underline display or blinking on the underline is being
executed. When UD = "L", it indicates neither of underline display nor blinking on the
underline is performed.
