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
