Abstract
A configuration to address a bus stall during data packet transmission also allows for bus recover due to data packet transmission errors. If a downstream node is not ready to receive data from a buffer of an upstream node, a timer counts a timeout value. The time count increments on each clock cycle in which the downstream node is not ready to receive data. The buffer is cleared at the upstream node when the count reaches a predetermined threshold value. Alternately, the configuration also operates to receive a packet header from an upstream node, the packet header identifying a number of data in a packet. If no data downstream is received on a clock cycle, a counter triggers and is incremented for each cycle in which no date is received. When a threshold is reached dummy data fills a data packet to then transmit the data.
