CS42416
6.17.2 DE-EMPHASIS SELECT BITS (DE-EMPHX)
Default = 00
00 - Reserved
01 - De-Emphasis for 32 kHz sample rate.
10 - De-Emphasis for 44.1 kHz sample rate.
11 - De-Emphasis for 48 kHz sample rate.
Function:
Used to specify which de-emphasis filter to apply when the “Force PLL Lock (FRC_PLL_LK)” on
page 49 is enabled.
6.17.3 INTERRUPT PIN CONTROL (INTX)
Default = 00
00 - Active high; high output indicates interrupt condition has occurred
01 - Active low; low output indicates an interrupt condition has occurred
10 - Open drain, active low. Requires an external pull-up resistor on the INT pin.
11 - Reserved
Function:
Determines how the interrupt pin (INT) will indicate an interrupt condition.

For all bits in this register, a “1” means the associated interrupt condition has occurred at least once since the reg-
ister was last read. A ”0” means the associated interrupt 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.
6.18.1 PLL UNLOCK (UNLOCK)
Default = 0
Function:
PLL unlock status bit. This bit will go high if the PLL becomes unlocked.
6.18.2 ADC OVERFLOW (OVERFLOW)
Default = 0
Function:
Indicates that there is an over-range condition anywhere in the CS42416 ADC signal path.
