External Reset.
Active low input that performs external hardware reset of device.
Resets all internal logic to a known state and forces the device reg-
isters to their default value. Clock outputs are tristated during reset.
The part must be programmed after a reset or power on to get a
clock output. See the Si53xx Family Reference Manual for details.
This pin has a weak pull-up.
No Connection.
Leave floating. Make no external connections to this pin for normal
operation.
Interrupt/CKIN1 Invalid Indicator.
This pin functions as a device interrupt output or an alarm output for
CKIN1. If used as an interrupt output, INT_PIN must be set to 1. The
pin functions as a maskable interrupt output with active polarity con-
trolled by the INT_POL register bit.
If used as an alarm output, the pin functions as a LOS (and option-
ally FOS) alarm indicator for CKIN1. Set CK1_BAD_PIN = 1 and
INT_PIN = 0.
0 = CKIN1 present
1 = LOS (FOS) on CKIN1
The active polarity is controlled by CK_BAD_POL. If no function is
selected, the pin tristates.
