Note: The reset pin(PORx)
may be controlled using a
digital logic level signal
supplied from the application
systemlevel.Whennot
drivenfrom an external logic
level the PORx pin must be
pulled high to 3.3Vdc Digital.

Note 2: Depending on the serial port address the user desires SERADD0 may be pulled up to 3.3Vdc
Digital or pulled down to Vss (digital GND) (as shown selects SIB address 0x64\0x65)
Note 3: The clock stop pin (XTALPD) may be controlled using a digital logic level signal supplied from
the application system. When not using the clock stop feature this pin should be pulled low to Vss
(digitalGND).
Note 4: VCM (Voltage, Common Mode) may be buffered and supplied to external circuitry that may
need a common mode voltage reference.
Note 5: Add 5.11K resistors to all PCM Tx and Rx pins and pullup to +3.3Vdc Digital.
