Detailed Description

SX1262 radio driver implementation for IO-Homecontrol.

Unlike the SX1276, the SX1262 does not provide Semtech's IoHomeOn mode for IO-Homecontrol. On SX1276 that mode handles key protocol details in hardware: CRC generation and checking, packet boundary handling, and delivery of already-decoded protocol bytes in the FIFO. On SX1262 those pieces are reproduced in software by SoftPhyDriverBase (shared with RadioLR1121) on top of generic GFSK support; this file supplies the SPI transport and every register/opcode encoding SoftPhyDriverBase's shared RX/TX orchestration calls through virtual primitives.

The chip interface itself is opcode-based SPI instead of the SX1276 register model, and every transaction must respect the BUSY line. For experiment builds, the RX path prioritizes preserving the chip-reported bytes and metadata verbatim.
