Interrupt/Alarm Output Indicator.
This pin functions as a maskable interrupt output with
active polarity controlled by the INT_POL register bit.
The INT output function can be turned off by setting
INT_PIN = 0. If the ALRMOUT function is desired
instead on this pin, set ALRMOUT_PIN = 1 and
INT_PIN = 0.
0 = ALRMOUT not active.
1 = ALRMOUT active.
The active polarity is controlled by CK_BAD_POL. If no
function is selected, the pin tristates.

Indicator.
Input: If manual clock selection is chosen, and if
Output: If CKSEL_PIN = 0, the CKSEL_REG register
Clock Input 4.
Differential clock input. This input can also be driven with
a single-ended signal. CKIN4 serves as the frame sync
input associated with the CKIN2 clock when
CK_CONFIG_REG = 1.
Clock Input 2.
Differential input clock. This input can also be driven with
a single-ended signal.
CKSEL_PIN = 1, the CKSEL pins control clock
selection and the CKSEL_REG bits are ignored.
If configured as inputs, these pins must not
float.
bits control this function.
If auto clock selection is enabled, then they
serve as the CKIN_n active clock indicator.
0 = CKIN3 (CKIN4) is not the active input clock
1 = CKIN3 (CKIN4) is currently the active input
to the PLL
The CKn_ACTV_REG bit always reflects the
active clock status for CKIN_n. If
CKn_ACTV_PIN = 1, this status will also be
reflected on the CnA pin with active polarity con-
trolled by the CK_ACTV_POL bit. If
CKn_ACTV_PIN = 0, this output tristates.
