Crystal or ceramic resonator output pin. Leave this pin unconnected
(floating) if external clock is used at Pin-3.
Crystal, ceramic resonator or external clock input pin.
Multi function Programmable SSCLK4 or REFOUT3 clock pin or PD#,
OE, SSON#, or FS control pin. Power Down (PD#-Active Low): If
PD#=0(Low) and Output Enable (OE-Active High).
If PD# or OE is programmed, the pin is weakly pulled high to VDD.
If SSON# or FS is programmed, the pin is weakly pulled low to VSS.
Power supply ground.
This pin can be programmed as SSCLK2 or REFCLK1 clock pin.
This pin can be programmed as SSCLK2 or REFCLK2.
