GREEN/
Switch-1
Green LED output and
Restore switch
CMOS
In/Out This signal is multiplexed:
GREEN:
Logic Green LED Signal (see
Chapter 3, Table 14). Not valid
until 500ms after startup. Active
low.
Switch-1:
If the level on this pin is pulled-
down with 1k&** the units goes
back to default serial settings.
The Restore Default input is
only active during the first
500ms after startup.
See the Serial Port Adapter AT
command Specification for
more information on the Re-
store switch.
See section A.2.3.2 for design
examples.
