SSSEL has internal pull-up and SSON has pull-down resistors.
In applications if a crystal is used for the input reference clock, refer to crystal manufacturer’s specifications for the required crystal load capacitor value.
Parameters are guaranteed by design and characterization. Not 100% tested in production. All parameters specified with fully loaded outputs. All outputs
loaded with 15 pF.
Measured between 0.2*VDD and 0.8*VDD Volts.
Triggering is done at 1.5V VDDC.
