3.19 Debug (DB40)
Table 3-4 lists the pin signals of the CN1 connector, which provides 40 pins, 1 row, consecutive
sequence with 0.02" (0.50mm) pitch.
P154
VDD_IN (Module power input voltage -
3.0V min to 5.25V max)
S155
FORCE_RECOV# (Low on this pin allows
non-protected segments of Module boot
device to be rewritten / restored from an
external USB Host on Module USB0. The
Module USB0 operates in Client Mode when
the Force Recovery function is invoked.
Pulled high on the Module. For SOCs that
do not implement a USB based Force
Recovery function, then a low on the Module
FORCE_RECOV# pin
may
invoke the SOC
native Force Recovery mode – such as over
a Serial Port. Pulled up on Module. Driven
by OD part on Carrier.)
P155
VDD_IN (Module power input voltage -
3.0V min to 5.25V max)
S156
BATLOW# (Battery low indication to
Module. Carrier to float the line in inactive
state. Pulled up on Module. Driven by OD
part on Carrier.)
P156
VDD_IN (Module power input voltage -
3.0V min to 5.25V max)
S157
TEST# (Held low by Carrier to invoke
Module vendor specific test function(s).
Pulled up on Module. Driven by OD part on
Carrier.)
S158
