DEFAULT DESCRIPTION
0
When enabled, the device will respond to slave address 0x58 (or 1011000). This is useful for
triggering multiple drivers at the same time.
0
Haptic Broadcast disable.
1
Haptic Broadcast enabled.
1
Enables/disables averaging for the resonance reporting located in LRA_PERIOD[9:0]
parameter.
0
LRA_PERIOD[9:0] reports the average period of the last 4 periods. Uses a shift
register preloaded with 0.
1
LRA_PERIOD[9:0] reports the last period.
1
Applies a compensation factor to compensate for variations of LDO shifting.

This parameter selects the function of the TRIG/INTZ pin. If this parameter is changed during
process execution, the device will go into standby.
0
Pin functions as external pulse trigger (input). In this mode, the GO bit can also be
used to trigger or cancel processes.
1
Pin functions as external level trigger - enable (input). In this mode the GO bit cannot
be used.
2
Pin functions as an interrupt (open drain output). In this mode, the GO bit is the only
mechanism to trigger and cancel processes.

This parameter is used to select the mode of operation. If the mode is changed during process
execution, the device will immediately go into standby.
