Fig.22-80. Bus shutdown resume (Normal mode operation with ABT)
Note When performing a reinitialization of the packet buffer by clearing the RDY bits before starting the bus
shutdown recovery sequence, all TRQ bits are cleared.
Note When a request is made to transition from initialization mode to any other mode of operation to
perform the bus shutdown recovery sequence again in the bus shutdown recovery sequence, the
Receive Error counter is cleared. Therefore, it is necessary to detect the 11 consecutive recessive
bits on the bus again 128 times.
