2.1.5 Noise Reduction Stop Setting
2.1.6 Noise Reduction Demo Mode Setting
OKI Semiconductor
Noise reduction can be forcibly stopped by setting NROFF (SUB:48h-bit[0]) on the I
However, data can be written into the memory even while noise reduction is stopped.
By setting NRDEMO[2:0] (SUB:48h-bit[2:0]), a screen can be split as shown in Figure F2-1-6 and noise
reduction function can be confirmed as demo mode or the I
However, the demo mode does not work when noise reduction is stopped by setting NROFF = 1.
