6.2 Hardware Configuration +WHCNF
6.2.1 Description
This Wavecom proprietary command allows to:
• Activate or deactivate the keypad functionality in the Wireless CPU ® where
available. When the keypad is deactivated, ten more I/0 pins will be free to be
used (see PTS documentation for more information)
The new setting will be taken into account immediately after the keypad
activation or deactivation. With the keypad activation, ten GPIO pins are
immediately used by the keypad and are not usable by other applications
• Activate or deactivate the flash LED (Activity status indication)
The new setting will be taken into account after a restart
If the software downloaded is either corrupted or non-compatible, the flash
LED is in "very quick flash" mode even if the flash LED is deactivated
• This command allows the user to activate or deactivate the 32 kHz clock to
output on a pin of the Wireless CPU ® . When the 32 kHz feature is deactivated,
one more I/0 pin will be free to be used (see PTS documentation for more
information)
The new setting will be taken into account immediately after the 32 kHz feature
activation or deactivation. With the 32 kHz feature activation, one I/O pin is
immediately used to output the clock and this pin is no more usable as an I/O
pin (until the 32 kHz feature will be deactivated)
• This command allows the users to activate or deactivate the management of
the SIM Voltage Indication pin use by an External SIM Switch to know the
power supply level to use as SIM Vcc. When the External SIM Switch feature is
deactivated, one more I/0 pin will be free to be used (see PTS documentation
for more information)
The new setting will be taken into account after a restart. The I/O pin is
allocated after the restart during the Wireless CPU ® initialisation
