Register description
The register value could be updated using the ATSn=m<cr> command and
displayed using ATSn?<cr> command.
At power-up, the previous transceiver configuration is restored from E2PROM
(non volatile) to RAM. The registers are located in RAM registers, any
modification is performed on RAM registers: To save current register
configurations, it is necessary to use the AT&W<cr> command (If not, the
updated parameters are lost in case of power shortage).
The registers are shared in 2 types : read only (R) or read/write (R/W)
exactly the same registers configuration in term of : hopping table
(S200),
parameters (S210, S211, S212, S213), handshake (S216), protocol
(S220) and packet retries (S221).
