SPI Byte
corrupt command. For example, if the EM260 resets during the Response Section, the Host will still clock out
the correct number of bytes. But when the host attempts to verify the value
it will see either the value
be discarded.
Table 15 lists the possible commands and their responses in the SPI Byte.
5.5.1
There are four primary SPI Bytes: SPI Protocol Version, SPI Status, Bootloader Frame, and EZSP Frame.

Note: The Length Byte only specifies the length of the Payload Frame. It does not include the Frame

SPI Protocol Version [0x0A]: Sending this command requests the SPI Protocol Version number from the SPI
Interface. The response will always have bit 7 set and bit 6 cleared. In this current version, the response

Response
EM260 reset occurred—This is never used in
another Response; it always indicates an EM260
Reset.
Oversized Payload Frame received—This is never
used in another Response; it always indicates an
overflow occurred.
Aborted Transaction occurred—This is never
used in another Response; it always indicates an
aborted transaction occurred.
Missing Frame Terminator—This is never used in
another Response; it always indicates a Missing
Frame Terminator in the Command.
Unsupported SPI Command—This is never used in
another Response; it always indicates an unsup-
ported SPI Byte in the Command.
[none]
bit[7] is always set. bit[6] is always cleared.
bit[5:0] is a number from 1–63.
bit[7] is always set. bit[6] is always set. bit[0]—
Set if Alive.
