Description
0 selects register 7 bit 2 to output at pin 4.
1 selects RX PN Sync to output at pin 4.
0 selects register 7 bit 3 to output at pin 5.
1 selects TX PN Sync to output at pin 5.
Allows the microcontroller to see why the unit came
awake, to allow proper response.

WAKE bits are cleared (set to 0) upon entering the
sleep mode. See section 2.2.
Direct sense of FLIPSW input pin 21. For example,
when the handset is already awake and the user wants
to hang up and start a new call, then the microcontroller
could sense this by scanning this bit. Not latched.
Direct sense of INTERCOM pin 51. For example, when
the handset is already awake and the user wants to
hang up and start an intercom call, then the
microcontroller could sense this by scanning this bit. Not
latched.
Not a user function.
Absolute Maximum Ratings*

*NOTICE: Stresses beyond those listed under “Absolute Maxi-
mum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the
device at these or any other conditions beyond those indi-
cated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions
for extended periods may affect device reliability.
