LED Controller Instruction:

SETPWM:

set the LEDx brightness, 0~255;

RAMP：

set the LEDx Fade in/out steps, 0~255;

SETSTEP:

set the LEDx RAMP step time;

The LED controller instruction supports register parameters and immediate data in internal SRAM mode. The

With the internal SRAM instruction, when the Rx/Ch is

‘11111’, the channel of CTRSR.bitx=0 is effective;

when Rx/Ch is

‘11110’, the channel of GMSKx=0 is effective.

When using the external I2C instruction, the LED controller instruction can only support immediate data mode.
