Register (0x52) contains the number of repetitions for z-axis.

Table 26 below shows the number of repetitions resulting out of the register configuration. The

performed number of repetitions nZ can be calculated from unsigned register value as nZ =

1+REPZ as shown below, where b7-b0 are the bits 7 to 0 of register 0x52:
