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.
Table 10 below summarizes the chip configuration programming:
By default the configuration set#1 is used and register RTParam_switch_ext is set to ‘0’.
Note that a new value of the ConfigSwitch register or at the SWITCH pin should be modified when the EN signal is
low. The actual switch to the newly selected set of SWParam register will be applied to the transceiver on the next
rising edge of the EN signal.
