Various kinds of RGB control can be implemented by designating waveform cycles, waveform patterns, current settings 1, 2
and rising/falling slope times.
To activate a RGB waveform, a continuous operation via RGB*EN or a single-shot operation via RGB*OS can be selected.
In addition, when control via the external terminal RGB*CNT is enabled via RGB*MEL, the corresponding LED can be lit in
synchronization with the external signal.

・ ingle cycle time is set for a waveform pattern.
・ This setting can be made independently for RGB1 and RGB2.
・ A pattern in a waveform cycle is set.
・ Sixteen types of waveform patterns can be set in units of waveform patterns.
・ For concrete waveform patterns, refer to the timing diagram shown on the next page.
・ Two currents in a waveform pattern are set.
・ When the maximum current value is 25.4mA, it is possible to set the current ranging from 0 to 25.4mA with an increment
・ The polarity of a waveform is determined by the greater-than/ less-than relationship in the current setting.
・ This setting can be made in units of terminals.
・ A current change time during switching between current settings 1 and 2 is set.
・ Regardless of current settings 1 and 2, a rising slope time applies at current increase and a falling slope time applies at
of 0.2mA (128 steps).
A time per step (0.2mA) is calculated based on a difference between the currents selected in current settings 1, 2 and a
setting slope time.
For this reason, a time per step (0.2mA) is short when a difference between setting currents I1 and I2 is large. In
contrast, it is long when a difference between setting currents I1 and I2 is small.
current decrease. For concrete waveform images, refer to the timing diagram shown on the next page.
When control via the external terminal RGB*CNT is enabled via RGB*MEL, lighting is enabled if the input external signal
goes “H.” In contrast, it is disabled if the external input signal goes “L.” In this way, synchronization with the external
signal is enabled so that LED can be blinked in conjunction with a ringing tone (a melody signaling a ringtone).
