Inputting Display Data
LED display
Display data is output to the LED1 to LED5 pins in correspondence with each bit by executing
the L. RLOAD command. Input data uses positive logic. When the data is 1, the LED lights.
When the data is 0, the LED goes off.
VF display (RAM direct display)
Set optional data in the digit register and the duty register, and execute the W.A.C LOAD
command to set the display digit position. Execute the DATA DISPLAY command to write the
b0 to b15 (*1) display data in the RAM. The write address counter is incremented by one. The
write address counter counts sequentially 0, 1, 2,------, 14, 15, 0, 1, ----- regardless of the value of
the digit register.

display data in the case of MSC7110-01.
Brightness Adjustment
The brightness can be adjusted by using the values of the duty cycle register (D.C.R) and the
digit register (D.R). The value of the duty cycle register changes the pulse width (B) at the D1
to D16 output pins, and the value of the digit register changes the cycle (A).
The table below gives the relation between the value of the duty cycle register and the duty.
When all the values of the duty cycle register are 0 (in the case of 16-digit display), the display
is blank.
