Positive power supply.
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 REFOUT4 clock pin or PD# or
OE 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.
Power supply ground.
This pin can be programmed as SSCLK1 or REFCLK1.
This pin can be programmed as SSCLK2 or REFCLK2.
Multi function Programmable SSCLK3 or REFOUT3 clock pin or SSON#
or FS control pin. Programmable SSON# or Frequency Select (FS)
Control pin. If SSCG# function is programmed: Spread-on=0(Low) or
Spread-off=1(High). If FS function is programmed: The clock frequencies
can be switched between two sets of frequencies as programmed.
If SSON# or FS is programmed, the pin weakly pulled low to VSS.
