Description
Single-ended REF output. 1.8V LVCMOS/LVTTL interface levels.
Core analog functions supply pin.
Crystal Input. Accepts a 10MHz-40MHz reference from a clock oscillator or a
12pF fundamental mode, parallel-resonant crystal.
Crystal Output. This pin should be connected to a crystal. If an oscillator is
connected to OSCI, then this pin must be left unconnected.
