When using a normally closed SIM or a normally open SIM card, the detection function can be set by
the AT command.
If AT+HOSCFG=1 is set, the status of the SIM card is high when the SIM card is in position, and
AT+HOSCFG=1 is set. When the SIM card is in the state, the status is low. Set AT+HOSCFG=0, 0 SIM card
hot swap function is off. .

Module wake up host
The CLM920_NC5 Mini PCIE module supports sleep wakeup. WAKEUP_IN wakes up for the host
control module sleep, WAKEUP_OUT wakes up the host for the module. When using, you need to set
AT^RPTFLAG=0 to enable the wake-up function (you need to set the boot every time).
WAKEUP_IN: This pin is the host wake-up module pin. When the WAKEUP_IN signal is pulled high to
1.8V, the host can wake up the module and pull the module down to enter sleep mode.
WAKEUP_OUT: This pin wakes up the host pin for the module. When there is a voice incoming call or a
short message needs to be reported, WAKEUP_OUT will output a rectangular wave to wake up the host.
