Ground Key Removal Detection Threshold.
Programs the longitudinal current threshold at which it is determined that a ground
key event has been terminated. 0 to 101.09 mA programmable range, 3.097 µ A/
LSB, 396.4 µ A effective resolution. Usable range is 0 to 16 mA.
Ground Key Filter Coefficient.
Programs the digital low-pass filter block in the ground key detection circuit. Refer to
"4.5.2. Ground Key Detection" on page 34 for calculation.
Q1/Q2 Thermal Low-pass Filter Coefficient.
Programs the thermal low-pass filter value used to calculate the power in transistors
Q1 and Q2. Also used to set thermal IPF when using Si3200. Refer to "4.4.6. Power
Filter and Alarms" on page 27 for use.
