Command and Response Protocol (continued)

7.5.1.1 Frame Initialization Byte

The Frame Initialization Byte is always the first byte of the frame. In all cases, the length of the frame can be

determined from this initial byte. Note that bit 7 identifies each frame as either a command frame or a response

frame. The initialization byte is defined as follows for each of the two Frame Init types:

Command Frame Init

FRM_TYPE = 1

REQ_TYPE

ADDR_SIZE

DATA_SIZE

Response Frame Init

FRM_TYPE = 0

RESP_BYTES-1

The descriptions for the fields shown in the frame initialization bytes are in Table 4.
