LRF

The Radio IP in charge of Low Power Radio communications.

Systimer

Timer running at a resolution of 250 [ns], used by the RCL for all scheduling-related operations.

LRF image

Protocol-specific firmware used by the LRF.

Command handler

Self contained state machine that takes care of the command parameters, the payload, and the interrupt handling needed during the execution of radio commands.

RCL event

Signals sent from the RCL to the command handlers (and vice versa) that contain information about the radio operation.

LRF event

Signals sent from the LRF to the command handlers and the RCL that contain information about radio-specific events.

PHY Config

Set of register values describing parameters of a specific radio PHY. Meant to be generated via a tool. It's uploaded to TRX as binary arrays which are then directly applied to TOPSM registers. Any specific settings are completely opaque to the TRX firmware.

PSDU

Physical (layer) Service Data Unit - often (for example in IEEE 802.15.4) used to describe PHY payload in communication protocols. This does not include any synchronization headers, PHY headers of footers. This does include MAC headers or footers and MAC payloads.
