COMP
Configuration Register 2 configures the test signal, clock, reference, and LOFF buffer.
Bit 7
Must be set to '1'
Bit 6
PDB_LOFF_COMP: Lead-off comparator power-down
This bit powers down the lead-off comparators.
0 = Lead-off comparators disabled (default)
1 = Lead-off comparators enabled
Bit 5
PDB_REFBUF: Reference buffer power-down
This bit powers down the internal reference buffer so that the external reference can be used.
0 = Reference buffer is powered down (default)
1 = Reference buffer is enabled
Bit 4
VREF_4V: Enables 4-V reference
This bit chooses between 2.42-V and 4.033-V reference.
0 = 2.42-V reference (default)
1 = 4.033-V reference
Bit 3
CLK_EN: CLK connection
This bit determines if the internal oscillator signal is connected to the CLK pin when an internal oscillator is used.
0 = Oscillator clock output disabled (default)
1 = Oscillator clock output enabled
Bit 2
Must be set to '0'
Bit 1
INT_TEST: Test signal selection
This bit determines whether the test signal is turned on or off.
0 = Off (default)
1 = On; amplitude = ±(VREFP – VREFN)/2420
Bit 0
TEST_FREQ: Test signal frequency.
This bit determines the test signal frequency.
0 = At dc (default)
1 = Square wave at 1 Hz
