5. Operation Modes
When operating the XE1203F, it might by useful to quickly switch between two pre-defined operating modes, to
save time and traffic on the 3-wire serial interface bus. This may occur when the XE1203F is required to switch
quickly between receive and transmit mode, when it has to operate on two different carrier frequencies, or when it
has to switch between the high linearity mode B and the high sensitivity mode A. For that purpose, the five
parameters stored in the SWParam Configuration Register are duplicated: the configuration set#1 and the
configuration set #2.
Depending on the ConfigSwitch 1-bit Register or the input level at the SWITCH pin, the XE1203F transceiver will
use either the SWParam configuration set#1 or the set #2. If the RTParam_Switch_ext configuration parameter is
low, then the SWParam configuration set is selected by the ConfigSwitch parameter – set#1 if ConfigSwitch is
“0”, set#2 if ConfigSwitch is “1”. If the RTParam_Switch_ext configuration parameter is high, then the SWParam
configuration set is selected by the SWITCH pin – set#1 if SWITCH is low, set#2 if SWITCH is high.
