The Reload Key command copies the key in non-volatile memory (NKN)

to the volatile location (NKV). This allows a sophisticated system to change

the keys during operation and quickly revert back to the default key.

The Non-volatile Reset command (FF 07 FE 47 20 FE 2A FE 3B) sets

all non-volatile registers to their default values. When the configuration is

reset, the following message, shown in quotes, is sent out the UART at the

current baud rate, then the module is reset, similar to a power cycle:

“\r\nConfiguration Reset\r\n”.

This reset can also be done by toggling the PB line as described in the

Restore Factory Defaults section.

SECSTAT - Security Status

Volatile Address = 0xC9

This volatile read-only register provides status of the security features.

The command returns a single byte. Figure 75 shows the meanings of the

bits in the returned value byte.

JOINST - Join Status

Volatile Address = 0xCA

This volatile read-only register shows the current or previous state of Join

activity since the module was last reset.

The command returns a single byte. Figure shows the meanings of the

returned value byte.
