2.5 Memory Organization
The MCC-6120 SDR has four types of memory:
Program Memory The Program Memory is non-volatile Flash memory (2Meg x 16). This is
also referred to as Flash1 in the documentation. It contains the
MBNET200 image software, the DSP image software, configuration, and
application software. These programs are installed at the MCC facilities at
the time of shipment. The information stored in the Program Memory is
referred to as “factory defaults”.
Parameter Memory The Parameter Memory is non-volatile Flash memory (2Meg x 16). This
is also referred to as Flash2. It contains the configuration data for the unit
such as the customer number, the serial number and ID of the MCC-6120
SDR and the authorized FCC frequencies it may use. This information is
normally programmed into the unit prior to shipment. The Script files are
also stored in Parameter memory, either at the MCC facilities or on site.
Calibration Memory The Calibration Memory is serial Electrically Erasable memory (8,192
Kbyte EEPROM) used to store specific parameters associated with the
calibration of the radio. These parameters are set when the radio is
manufactured and/or when it is recalibrated by trained technicians in a
laboratory. They cannot be changed in the field. These parameters
include:
freqcal Calibrates the 19.2 MHz TCXO
lb_rx-gain Calibrates the Low Band RSSI (detrf)
hb_rx-gain Calibrates the High Band RSSI (detrf)
hb_tx-gain Calibrates the High Band Tx gain
When the unit is rebooted by entering the BOOT command, or whenever
the unit is power cycled, the ColdFire software will reload these
