SINGLE CHIP 868MHZ TO 956MHZ RF TRANSCEIVER
The Physical Layer Management Entity (PLME) provides layer management service interfaces through which
layer management functions may be invoked. The figure below shows the different modes of operation that
can be invoked by the PLME.
The modes of operation can be invoked via the MODEM_REQUEST register and the status can be read from
the MODEM_CONF0 and MODEM_CONF1 registers.
