RST
I LVCMOS 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 dis-
abled during reset. The part must be programmed after a reset
or power-on to get a clock output. See Family Reference Man-
ual for details.
This pin has a weak pull-up.
Note: Internal register names are indicated by underlined italics, e.g., INT_PIN. See Si5369 Register Map.
