CLK_DIV  
This register stores the status of whether the positive or negative electrode on each channel is on or off. See the  
Lead-Off Detection subsection of the ECG-Specific Functions section for details. Ignore the LOFF_STAT values  
if the corresponding LOFF_SENS bits are not set to '1'.  
'0' is lead-on (default) and '1' is lead-off. When the LOFF_SENS bits[3:0] are '0', the LOFF_STAT bits should be  
ignored.  
Bit 7  
Bit 6  
Must be set to '0'  
CLK_DIV : Clock divider selection  
This bit sets the modultar divider ratio between fCLK and fMOD. Two external clock values are supported: 512 kHz and  
2.048 MHz.  
0 = fCLK and fMOD/4 (default, use when fCLK = 512 kHz)  
1 = fCLK and fMOD/16 (use when fCLK = 2.048 MHz)  
Bit 5  
Bit 4  
Must be set to '0'  
RLD_STAT: RLD lead-off status  
This bit determines the status of RLD.  
0 = RLD is connected (default)  
1 = RLD is not connected  
Bit 3  
Bit 2  
Bit 1  
Bit 0  
IN2N_OFF: Channel 2 negative electrode status  
This bit determines if the channel 2 negative electrode is connected or not.  
0 = Connected (default)  
1 = Not connected  
IN2P_OFF: Channel 2 positive electrode status  
This bit determines if the channel 2 positive electrode is connected or not.  
0 = Connected (default)  
1 = Not connected  
IN1N_OFF: Channel 1 negative electrode status  
This bit determines if the channel 1 negative electrode is connected or not.  
0 = Connected (default)  
1 = Not connected  
IN1P_OFF: Channel 1 positive electrode status  
This bit determines if the channel 1 positive electrode is connected or not.  
0 = Connected (default)  
1 = Not connected
