Power supply input
CNVSS
Apply 3.3 ± 0.3 V to the Vcc pin (for both 5V and 3.3V versions) and 0 V to
the Vss pin.
I Connect this pin to VCC.
Reset input
Clock input
Clock output
BYTE
I Reset input pin. When reset is held low, more than 20 cycles of clock are
required at the XIN pin.
I _{Connect a ceramic or crystal resonator between the XIN and XOUT pins.}
O
When entering an externally derived clock, enter it from XIN and leave
XOUT open.
I Connect this pin to Vcc or Vss.
Analog power supply input
Connect AVSS to Vss and AVcc to Vcc, respectively.
Reference voltage input
O Enter the reference voltage for AD from this pin.
