SDA and SCL have pull-up resistors in Module,2 external pull up resistors are reserved.
3.6 WoWWAN#
The WoWWAN# pin is an open drain signal which can be used as an interrupt signal to the host. Normally
it will keep high logic level until certain conditions such as receiving SMS, voice call (CSD, video) or URC
reporting, then WoWWAN# will change to low logic level to inform the host (client PC), the pulse time is 1
second.
