0x23 - 0x25: PULSE_THSX, Y, Z Pulse Threshold for X, Y & Z Registers
The pulse threshold can be set separately for the X, Y and Z axes. The PULSE_THSX, PULSE_THSY and PULSE_THSZ
registers define the threshold which is used by the system to start the pulse detection procedure.

Table 41. PULSE_THSZ Description
THSZ[6:0]
Pulse Threshold on Z-axis. Default value: 000_0000.
The threshold values range from 1 to 127 with steps of 0.63g/LSB at a fixed 8g acceleration range, thus the minimum
resolution is always fixed at 0.063g/LSB. If the Low Noise bit in Register 0x2A is set then the maximum threshold will be 4g. The
PULSE_THSX, PULSE_THSY and PULSE_THSZ registers define the threshold which is used by the system to start the pulse
detection procedure. The threshold value is expressed over 7-bits as an unsigned number.

Table 42. PULSE_TMLT Description
TMLT[7:0]
Pulse Time Limit. Default value: 0000_0000.
The bits TMLT7 through TMLT0 define the maximum time interval that can elapse between the start of the acceleration on the
selected axis exceeding the specified threshold and the end when the acceleration on the selected axis must go below the
specified threshold to be considered a valid pulse.
The minimum time step for the pulse time limit is defined in Table 43 and Table 44 . Maximum time for a given ODR and
Oversampling mode is the time step pulse multiplied by 255. The time steps available are dependent on the Oversampling mode
and whether the Pulse Low Pass Filter option is enabled or not. The Pulse Low Pass Filter is set in Register 0x0F.
