Table 26. S4S_TPH_L register description

TPH_H_SEL

Chooses if the TPH formula must be taken into account (see equation below).

TPH_L_[6:0]

S4S timeframe expressed in number of samples as described in the equation below.

If TPH_H_SEL=0 and TPH_L_[6:0] = d0, S4S is disabled.

When TPH_H_SEL = 0: TPH [#Samples] = 2 x TPHL

When TPH_H_SEL = 1: TPH [#Samples] = 2 x (TPH_L + 256 x TPH_H)

Table 28. S4S_TPH_H register description

TPH_H_[7:0]

S4S time frame expressed in number of samples. Only if the TPH_H_SEL bit in S4S_TPH_L (04h) is high, is

the value of this register taken into account as described in the equation in S4S_TPH_L (04h)

S4S_RR (06h)

Sensor synchronization resolution ratio register (r/w)
