Flash information area (FIA)
The SN260 also includes a separate 1024-byte FIA that can be used for storage of data
during manufacturing, including serial numbers and calibration values. Programming of this
special Flash page can only be enabled using the SIF interface to prevent accidental
corruption or erasure. The EmberZNet stack reserves a small portion of this space for its
own use and in addition makes eight manufacturing tokens available to the application.
Encryption accelerator
The SN260 contains a hardware AES encryption engine that is attached to the CPU using a
memory-mapped interface. The CBC-MAC and CTR modes are implemented in hardware,
and CCM* is implemented in software. The first two modes are described in the IEEE
802.15.4-2003 specification. CCM* is described in the ZigBee Specification (ZigBee
Document 053474). The EmberZNet stack implements a security API for applications that
require security at the application level.
nRESET signal
When the asynchronous external reset signal, nRESET (Pin 13), is driven low for a time
greater than 200ns, the SN260 resets to its default state. An integrated glitch filter prevents
noise from causing an inadvertent reset to occur. If the SN260 is to be placed in a noisy
environment, an external LC Filter or supervisory reset circuit is recommended to guarantee
the integrity of the reset signal.
When nRESET asserts, all SN260 registers return to their reset state. In addition, the
SN260 consumes 1.5mA (typical) of current when held in RESET.
Reset detection
The SN260 contains multiple reset sources. The reset event is logged into the reset source
register, which lets the CPU determine the cause of the last reset. The following reset
causes are detected:

Power-on-reset
Watchdog
PC rollover
Software reset
