Figure 4.1 –LRM2 +PA Radio The Silicon Labs ERF32FG13 SoC is located between the host interface and the RF interface, providing decoupling between host and RF interface. The EFR32FG13 SoC has sufficient buffer space for one telegram. As shown later, telegram processing is defined to minimize delays, so to provide a “transparent-like” behavior.
LRM2+PA Radio Module Document p/n: 9S02-8969-A003 Rev.A 4.2 Functional Description - The LRM2 Radio Module is used to communicate telegrams between hosts. In Unity context, hosts are OCU and MCU CPU boards. The LRM2 has two interfaces: a Host Interface and a RF Interface. - Transmit and Received Telegrams are relayed through the LRM2 Host Data Buffer. This buffer is capable to hold only one telegram at a time.

LRM2&PA Configuration Concept LRM2&PA Configuration Concept All LRM2&PA configuration and status parameters are accessible through addressable registers. - All parameters can be read and written only in CONFIG mode. The definition of the configuration registers is given in reference [3]. This section addresses the basic description of all these three methods. 5.
