ecgamp_fast_startup

ECG reference amplifier fast startup.

0: Normal startup

1: Fast startup

ecgamp_gm_high

ECG reference amplifier high gm.

0: Normal gain

1: High gain

ecgamp_leadoff_en

This bit programs the value of the signal during the

ECGAMP signal measurement phase.

measurement

1: Leadoff current enabled during the ECGAMP signal

measurement

1:0

ecgamp_leadoff_pol

These bits define how the signal behaves during leadoff

detection sequence:

00: The ecgamp_leadoff_pol signal is low all the time

during leadoff detection sequence.

01: The ecgamp_leadoff_pol signal is high all the time

during leadoff detection sequence.

10: The ecgamp_leadoff_pol signal toggles after each

lead measurement during leadoff detection sequence,

but the first value is 0.

11: The ecgamp_leadoff_pol signal toggles after each

lead measurement during leadoff detection sequence,

but the first value is 1.
