Bit Description

irq_ecg_threshold

R_PUSH1

If programmed ecg_leadsdet_pol=0,

the ecg ADC value was below the

programmed ecg_threshold_low

setting

If programmed ecg_leadsdet_pol=1,

the ecg ADC value was above the

programmed ecg_threshold_high

setting

The STATUS2 register shows the current state of the interface. Some bits in here can trigger an

interrupt.

In normal mode, an asserted bit can be cleared by writing a '1' to it (in normal mode).

In clear-on-read mode, reading the STATUS2 register clears all bits.
