RING Voltage Filter Coefficient.
Programs the digital low-pass filter block that filters the voltage measured on the
RING lead used to determine battery switching threshold.
Speedup Threshold—High Byte.
Programs the upper byte of the threshold at which speedup mode in enabled. The
CMLOTH RAM location holds the lower byte of this value.
Speedup Threshold—Low Byte.
Programs the lower byte of the threshold at which speedup mode in enabled. The
CMHITH RAM location holds the upper byte of this value.
