The DP1283 RF transceiver has 2 main operating modes (Mode 1, Mode 2); each mode is then divided into 4 modes as
shown on the table below. Switching between Mode1 and Mode 2 can be done either by the 8-bit microcontroller
through the 3-wire bus (Chip_config register) or by using the pin SWITCH. The selection depends on the Switch_ext
which is an XE1283 register (RF circuit).
For more information about the DP1283 operating modes, please refer to the XE1283 Datasheet on the Semtech
website.
