Command Packet

A command packet is defined as a sequence of UART

characters originating at the host. Each packet starts with

a preamble character, followed by data characters, and

ending with a stop character (see Figure 31). After send-

ing a packet, the host either goes into idle mode or sends

another packet.

Preamble Character

The preamble is a framing character that signals the

beginning of a command packet. It is transmitted as an

unencoded 15h with a logic-one parity bit and a balanced

duty cycle. If any bit(s) other than the stop bits deviate

from the unique preamble sequence, the character is

not interpreted as a valid preamble, but rather as a data

character.
