5. Set AC address.....................................<Specifies the DCRAM and ADRAM addresses for AC.>

Code

*: Don’t care.

DA0 to DA5: DCRAM address

DA0....................LSB (least significant bit)

DA5....................MSB (most significant bit)

RA0 to RA3: ADRAM address

RA0 ....................LSB

RA3 ....................MSB

This instruction loads the 6-bit DA0 to DA5 DCRAM address and the 4-bit RA0 to RA3 ADRAM address into AC.

6. Intensity adjustment .............................<Adjusts the VFD intensity.>

DC0 to DC7: Duty cycle data (intensity adjustment data)

DC0 ....................LSB

DC7 ....................MSB

The data in the 8 bits DC0 to DC7 sets the VFD intensity to one of 240 levels. Since the value in the duty cycle

register is undefined immediately after power is applied, the display intensity is not determined at that point.

Therefore, applications must execute this instruction before turning on the display. Applications can adjust the

intensity using the duty cycle register and grid register. The duty cycle register value sets the pulse width (A) and the

grid register value sets the period (B). See Figure 3 for the grid timing chart details.
