Figure 3-7 illustrates the external drive circuit recommended for the WAKEUP_IN pin.
Alternatively, the 1.8 V IO of an external AP can be used to directly communicate with the
WAKEUP_IN pin.

Note that the WAKEUP_IN signal cannot wake theZM8300G module that is in the PSM
deep sleep state.
3.4.5
WAKEUP_OUT Signal
WAKEUP_OUT for ZM8300G module is used to wake up AP,default state is low level.when
the signal should be 100ms high level,which wake up AP.
3.4.6
PSM_MON Signal
PSM mode is UE Power Saving Mode. The fake power off state is applied in 3GPP REL12.
The module is on the register state but signalling can not be achieved. The attach or PDN
connection is not needed. The purpose is to save the power. Terminal calling is not needed
to answer immediately.when the terminal could get teminal calling service or date
transmission for actived state. The function should be supported for network.
For the waking up from PSM,ZM8300G could positively be waked up,besides the module
could be automatically waked up according to TAU TIME protocol. The module in PSM
state could be waked up for triggering the POWN_ON or PIN35 RESERVED no matter that
the timer of TAU is full or not.
The spcific trigger mode is same as power on sequence. The user could wake up the
module from external AP but should note that the RESERVED is multiplex pin. If the user
would like to use the function,please contact the ZTE FAE team in advance.
The PSM_MON is the indication signal for PSM mode.when the module is on the PSM
mode.the output of PSM_MON is low;when the module is on activeted mode,the output of
