Bit Description

ecg_leadsdet_sync_adc

ECG Leads Detection Automatic

Update. If this is asserted, then

ecg_leadsdet_pol is inverted

automatically at the start of a sequence

(at count=2) if in this sequence the

ADC will convert the ECGi channel.

ecg_leadsdet_pol

ECG Leads Detection Polarity. Can be

written to manually if

ecg_leadsdet_sync_adc is clear,

otherwise it is automatically toggled.

ecg_threshold_low

If the ADC returns an ECG value below

agc_threshold_low (not equal) at

ecg_leadsdet_pol=0, then the lead_off

interrupt can be triggered.
