PC1 controls the operating mode of the KXCJK.
0 = stand-by mode
1 = operating mode
RES determines the performance mode of the KXCJK. Note that to change the value of this
bit, the PC1 bit must first be set to “0”.
0 = low current, 8-bit valid. Only available for ODR <= 200 Hz. Bandwidth (Hz) = 800
1 = high current, 12-bit or 14-bit valid. Bandwidth (Hz) = ODR/2
DRDYE enables the reporting of the availability of new acceleration data as an interrupt. Note
that to change the value of this bit, the PC1 bit must first be set to “0”.
0 = availability of new acceleration data is not reflected as an interrupt
1 = availability of new acceleration data is reflected as an interrupt
GSEL1, GSEL0 selects the acceleration range of the accelerometer outputs per Table 13.
Note that to change the value of this bit, the PC1 bit must first be set to “0”.

WUFE enables the Wake Up (motion detect) function. 0= disabled, 1= enabled. Note that to
change the value of this bit, the PC1 bit must first be set to “0”.
0 = Wake Up function disabled
1 = Wake Up function enabled
1 _{This is a 14-bit mode available only in Full Power mode and only for Registers 0x06h-0x0Bh}
