Data Format
The data format, also referred to as a command , is the same for both the Command section and the Response
section. The data format of the SPI Protocol is straightforward, as illustrated in Figure 8.
SPI Byte

Error
Payload Frame (Variable Length)

Terminator
Figure 8. SPI Protocol Data Format
The total length of a command must not exceed 136 bytes.
All commands must begin with the SPI Byte . Some commands are only two bytes—that is, they contain the SPI
Byte and Frame Terminator only.
The Length Byte is only included if there is information in the Payload Frame and the Length Byte defines the
length of just the Payload Frame. Therefore, if a command includes a Payload Frame, the Length Byte can
have a value from 2 through 133 and the overall command size will be 5 through 136 bytes. The SPI Byte can
be a specific value indicating if there is a Payload Frame or not, and if there is a Payload Frame, then the
Length Byte can be expected.
The Error Byte is used by the error responses to provide additional information about the error and appears in
place of the length byte. This additional information is described in the following sections.
The Payload Frame contains the data needed for operating EmberZNet PRO. The EZSP Frame and its format
are explained in document UG100, EZSP Reference Guide . The Payload Frame may also contain the data
needed for operating the bootloader, which is called a Bootloader Frame. Refer to document UG103.6, Ember
Application Development Fundamentals: Bootloading , for more information on the bootloader.
The Frame Terminator is a special control byte used to mark the end of a command. The Frame Terminator
byte is defined as 0xA7 and is appended to all Commands and Responses immediately after the final data
byte. The purpose of the Frame Terminator is to provide a known byte the SPI Protocol can use to detect a
