Latches device status and
counters, typically at 1-second
intervals.
Resets the device when asserted
low.
8 kHz clock input used to derive
OneSecOut (pin B6).
One-second pulse derived from the
Ref8KClk input.
Optional 155.52 or 622.08 MHz
clock for use as the transmit clock
as controlled by the CLKREC
register.
Allows the use of an externally
generated 155.52 MHz clock as
selected in the CLKREC register.
The external source must be
accurate to 20 PPM.
