9.5.1.2 Packet Identifier Field
MC68HC908JB8•MC68HC08JB8•MC68HC08JT8 — Rev. 2.3
Freescale Semiconductor
The start of a packet (SOP) is signaled by the originating port by driving
the D+ and D– lines from the idle state (also referred to as the J state) to
the opposite logic level (also referred to as the K state). This switch in
levels represents the first bit of the sync field.
signaling and voltage levels for the start of packet and the sync pattern.
The packet identifier field is an 8-bit number comprised of the 4-bit
packet identification and its complement. The field follows the sync
pattern and determines the direction and type of transaction on the bus.
