10.2.1.6 End Of Packet (EOP)
The single-ended 0 (SE0) state is used to signal an end of packet (EOP). The
single-ended 0 state is indicated by both D+ and D- being below 0.8 V. EOP will be
signaled by driving D+ and D- to the single-ended 0 state for two bit times followed
by driving the lines to the idle state for one bit time. The transition from the single-
ended 0 to the idle state denes the end of the packet. The idle state is asserted
for one bit time and then both the D+ and D- output drivers are placed in their
high-impedance state. The bus termination resistors hold the bus in the idle state.
Figure 10-8 shows the data signaling and voltage levels for an end of packet
transaction.
