13.30.5 Functional Description

The RFCTRL module is intended to flexibly route the PA/LNA and antenna diversity front-end control signals, as well as, the RX/TX frame time stamping to alternate pin functions of the Cortex-M0+ CPU without any further software action required after initialization of the alternate pin function output.

The module provides six 2-bit registers that control the muxing of the DIG1, DIG2, DIG3 and DIG4 front-end control signal outputs of the integrated transceiver to alternate pin functions of the SAM R30 device.
