6.2.6
Some of the non-volatile storage on the EM260 is made available for use by the Host. Up to 8 manufacturing
tokens stored in the Flash Information Area can be read using the
stored in the Simulated EEPROM can be read and written using the
token is 8 bytes. Tokens preserve their values between reboots. Refer to section 4.6.2 for a description of the
Simulated EEPROM and write cycle estimates.
6.2.7
Some of the RAM on the EM260 can be reserved by the Host for its own use. The amount of space reserved is

6.2.8
The Frame Control Byte of every response sent by the EM260 contains two status bits:
You can use the

The Host can obtain a random number from the EM260 using the
number is generated from analog noise in the radio and can be used to seed a random number generator on
the Host.
6.2.10 Radio Channel Calibration
Calibration information is stored in non-volatile memory on the EM260 for each radio channel. A channel
must be calibrated before being used for the first time. The EM260 will return a status value of
EMBER_CHANNEL_NOT_CALIBRATED
The channel calibration process can take several seconds to complete. The Host initiates this one-time
process using the
calibrationCompleteHandler
All EZSP frames begin with a Frame Control Byte. Table 19 describes the meaning of this byte for command
and response frames. Table 20 describes the sleep modes, Table 21 describes the overflow status bit and
Table 22 describes the truncated status bit. The second byte of all EZSP frames is the Frame ID Byte.
The overflow bit is set if the EM260 ran out of memory at any time since the previous response was sent. If
this bit is set, then messages may have been lost.
The truncated bit is set if the EM260 truncated the current response. If this bit is set, the command from
the Host produced a response larger than the maximum EZSP frame length.
