When in a power down mode, the following resources will cause interrupts that will wake
the MC891G and cause it to attempt complete the function associated with the interrupt.
Simultaneous interrupts will cause sequential completion of each associated function. These
interrupts include:
Report timer
GPIO change
Battery threshold
Heartbeat
Watchdog
Power-up
The related interrupt function will be attempted for a total duration set the associated
parameter in the power mode command.
4.4 AT Command
MC891G commands are AT extensions specific to MC891G devices. They are closely based on
commands that are as similar as possible to other industry common devices and are
essentially subsets of standard ION commands. Common commands used with CDMA
modems supporting IP connectivity are not included within the MC891G command set
extensions. These commands are left in their native structure, as defined by the respective
baseband CDMA chip supplier which product already in use.
Command Summary
The following commands are highly specialized to the MC891G. The commands listed are
intended to be similar to counterparts found in common CDMA modem command
extension.
