During a Display Data Write, the function of the I/D and others will not be altered even if the cursor

is not present. Please refer to the figure below.

Cursor

B : Blinking Control Bit

When B is set to '1", the character specified by the cursor blinks. The blinking feature is

displayed by switching between the blank dots and the displayed character at a speed of

409.6ms intervals when the fcp or fosc is 250kHz. Please refer to the figure below.

Figure 1

Figure 2

Note: Figure 1 and 2 are alternately displayed

The cursor and the blinking can be set to display at the same time. The blinking frequency

depends on the fosc or the reciprocal of fcp.

To illustrate, when fcp =270kHz, then, the blinking frequency = 409.6 x 250/270 = 379.2ms
