2.3.3 2DLPF Noise Reduction Auto ON/OFF
By setting AYLPF[2:1](SUB:65h-bit[7:6]) and ACLPF[2:1](SUB:66h-bit[7:6]) in the I2C-bus interface, the
noise reduction ON/OFF function can be set using the noise checking flag (YDTO1, YDTO2, CDTO1, CDTO2).
When using the automatic ON/OFF function, set YLPFON = 0 and CLPFON = 0.
