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 370-ms intervals when f
cp
or f
OSC
is
270 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 f
cp
is 300 kHz, 370
×
270/300 = 333 ms.)
Extended Function Set
When the extended register enable bit (RE) is 1, FW, B/W, and NW bit shown below are accessed. Once
these registers are accessed, the set values are held even if the RE bit is set to zero.
FW:
When FW is 1, each displayed character is controlled with a 6-dot width. The user font in CGRAM
is displayed with a 6-bit character width from bits 5 to 0. As for fonts stored in CGROM, no display area
is assigned to the leftmost bit, and the font is displayed with a 5-bit character width. If the FW bit is
changed, data in DDRAM and CGRAM SEGRAM is destroyed. Therefore, set FW before data is written
to RAM. When font width is set to 6 dots, the frame frequency decreases to 5/6 compared to 5-dot time.
See “Oscillator Circuit” for details.
B/W:
When B/W is 1, the character at the cursor position is cyclically displayed with black-white
invertion. At this time, bits C and B in display on/off control register are “Don’t care”. When f
CP
or f
OSC
is
270 kHz, display is changed by switching every 370 ms.
NW:
When NW is 1, 4-line display is performed. At this time, bit N in the function set register is “Don’t
care”.
Note:
After changing the N or NW or LP bit, please issue the return home or clear display instructions
to cancel to shift display.
