Firmware download, configuration (static/dynamic), and
monitoring/debugging
WLC1150 IC is a programmable controller, which supports downloading the updated/modified configuration
data and downloading the firmware. It also supports monitoring the firmware parameters and dynamic tuning
of the firmware parameters. The WLC1150 controller supports these features through CC and/or I2C interfaces
based on the input power type supported in the current firmware, which is stored in the flash. See
understand the communication interface (CC/I2C) to use based on the current firmware type.
