Register 73: Contains the least significant byte of the pre-arm reading count.

Register 75: Contains the most significant byte of the pre-arm reading count.

Pre-Arm Reading Count Register power-On/Reset Settings

At power-on or following a reset, the digitizer is set for 0 pre-arm readings. When the pre-arm reading mode is set (base +4B16 bit 3 set to ’1’), the digitizer is set for 3 pre-arm readings.
