This register selects the positive and negative side from each channel for lead-off detection. See the Lead-Off

Detection subsection of the ECG-Specific Functions section for details. Note that the LOFF_STAT register bits

should be ignored if the corresponding LOFF_SENS bits are set to '1'.

Bits[7:6]

Must be set to '0'

Bit 5

FLIP2: Current direction selection

This bit controls the direction of the current used for lead-off derivation for channel 2.

0 = Disabled (default)

1 = Enabled

Bit 4

FLIP1: Current direction selection

This bit controls the direction of the current used for lead-off derivation for channel 1.

0 = Disabled (default)

1 = Enabled

Bit 3

LOFF2N: Channel 2 lead-off detection negative inputs

This bit controls the selection of negative input from channel 2 for lead-off detection.

0 = Disabled (default)

1 = Enabled

Bit 2

LOFF2P: Channel 2 lead-off detection positive inputs

This bit controls the selection of positive input from channel 2 for lead-off detection.

0 = Disabled (default)

1 = Enabled

Bit 1

LOFF1N: Channel 1 lead-off detection negative inputs

This bit controls the selection of negative input from channel 1 for lead-off detection.

0 = Disabled (default)

1 = Enabled

Bit 0

LOFF1P: Channel 1 lead-off detection positive inputs

This bit controls the selection of positive input from channel 1 for lead-off detection.

0 = Disabled (default)

1 = Enabled
