7.12.1 Invert Signal Polarity (INV_AINX)
Default = 0
0 - Disabled
1 - Enabled
Function:
When enabled, these bits will invert the signal polarity of their respective channels.

For all bits in this register, a “1” means the associated error condition has occurred at least once since the
register was last read. A”0” means the associated error condition has NOT occurred since the last reading
of the register. Reading the register resets all bits to 0. Status bits that are masked off in the associated
mask register will always be “0” in this register.
7.13.1 CLOCK ERROR (CLK ERROR)
Default = x
Function:
Indicates an invalid MCLK to FS ratio. This status flag is set to “Level Active Mode” and becomes active
during the error condition. See “System Clocking” on page 31 for valid clock ratios.
7.13.2 ADC Overflow (ADCX_OVFL)
Default = x
Function:
Indicates that there is an over-range condition anywhere in the CS42432 ADC signal path of each of the
associated ADC’s.
