Note: The content of this section will be provided in a future revision of
the document.
GPIO40/POWER_SHDN 90 In/Out 1V8 GPIO, emergency power shutdown
signal (Input) in option. In
emergency powershutdown mode,
1 kOhm PU needed, pin should be
forced low level to trigger
emergency shutdown procedure.
Note that this feature is currently
not available.
GPIO2/POWER_MON 6 In/Out 1V8 GPIO or Power monitor (Output) in
option.POWER_MON is high right
after POWER_ON, then remains
high until shutdown procedure is
completed. Module can be safely
electrically power off as soon as
POWER_MON goes low. Note that
this feature is currently not
available.
GPIO26/CLK2 91 In/Out 1V8 Optional UART2 CLK (I/O)
alternate function to GPIO. See
Section UART2 Interface.
GPIO21 95 In/Out 1V8
GPIO23 93 In/Out 1V8
GPIO29/32KHZ_CLK_OUT 103 In/Out 1V8 Optional 32 kHz (Output)
GPIO42/SAR_DETECT 105 In/Out 1V8 GPIO, SAR detection signal (Input,
active low) in option. In this SAR
detection mode, 1 kOhm PU
needed. Note that this feature is
currently not available.
