(1) The functionality of the status 0 and status 1 pin in SPI and I2C mode is programmable.
(2) The REF_SEL input pin selects the primary or secondary input in MANUAL mode. If the system only requires one input, the second input stage power supply can be connected to GND to
minimize device power consumption. So if the system only uses a XTAL on the secondary input, REF_SEL should be tied to VDD.
For all pin modes, STATUS0 outputs the PLL_LOCK signal and STATUS1 the LOSS OF REFERENCE.
General Note: in all PIN MODEs, All voltage supplies must either be 1.8 V or 2.5/3.3 V and the PWR pin number 44 must be set 0 or 1 accordingly. In SPI and I2C mode, the supply
voltages can be "mixed and matched" as long as the corresponding register bits reflect the supply voltage setting for each desired 1.8 V or 2.5/3.3 V supply. Exception: inputs configured
for LVDS signaling (Type = LVDS) are supply agnostic, and therefore can be powered from 2.5 V/3.3 V or 1.8 V regardless of the supply select setting of pin number 44.
