Ground.
This pin must be connected to system ground. Minimize the
ground path impedance for optimal performance.
CKIN1 Invalid Indicator.
This pin performs the CK1_BAD function if CK1_BAD_PIN = 1
and is tristated if CK1_BAD_PIN = 0. Active polarity is con-
trolled by CK_BAD_POL.
0 = No alarm on CKIN1.
1 = Alarm on CKIN1.
CKIN2 Invalid Indicator.
This pin performs the CK2_BAD function if CK2_BAD_PIN = 1
and is tristated if CK2_BAD_PIN = 0. Active polarity is con-
trolled by CK_BAD_POL.
0 = No alarm on CKIN2.
1 = Alarm on CKIN2.
CKIN3 Invalid Indicator.
This pin performs the CK3_BAD function if CK3_BAD_PIN = 1
and is tristated if CK3_BAD_PIN = 0. Active polarity is con-
trolled by CK_BAD_POL.
0 = No alarm on CKIN3.
1 = Alarm on CKIN3.
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 ALRM-
OUT 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.
