36
B:
The character indicated by the cursor blinks when B is 1 (Figure 13). The blinking is displayed as
switching between all blank dots and displayed characters at a speed of 320-ms intervals when f
cp
or f
OSC
is
320 kHz. The cursor and blinking can be set to display simultaneously. (The blinking frequency changes
according to f
OSC
or the reciprocal of f
cp
. For example, when fcp is 270 kHz, 320
×
320/270 = 379.2 ms.)
Cursor or Display Shift
Cursor or display shift shifts the cursor position or display to the right or left without writing or reading
display data (Table 8). This function is used to correct or search the display. In a 2-line display, the cursor
moves to the second line when it passes the 40th digit of the first line. Note that the first and second line
displays will shift at the same time.
When the displayed data is shifted repeatedly each line moves only horizontally. The second line display
does not shift into the first line position.
The address counter (AC) contents will not change if the only action performed is a display shift.
Function Set
DL:
Sets the interface data length. Data is sent or received in 8-bit lengths (DB7 to DB0) when DL is 1,
and in 4-bit lengths (DB7 to DB4) when DL is 0.
When 4-bit length is selected, data must be sent or received twice.
N:
Sets the number of display lines (Table 9).
F:
Sets the character font (Table 9).
Note:
Perform the function at the head of the program before executing any instructions (except for the
read busy flag and address instruction). From this point, the function set instruction cannot be
executed unless the interface data length is changed.
Set CGRAM Address
Set CGRAM address sets the CGRAM address binary AAAAAA into the address counter.
Data is then written to or read from the MPU for CGRAM.
