External Reset.
Active low input that performs external hardware reset of
device. Resets all internal logic to a known state and forces
the device registers 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 Family Refer-
ence Manual for details.
This pin has a weak pull-up.
No Connect.
This pin must be left unconnected 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 controlled by the INT_POL register
bit.
If used as an alarm output, the pin functions as a LOS (and
optionally 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 func-
tion is selected, the pin tristates.
