PM7380

If a host incorrectly attempts a read multiple command whose address range spans beyond a point 4K bytes from the start of the FREEDM-32P672 register space, the FREEDM-32P672 may not issue a PCI disconnect and the PCI bus may hang.

The FREEDM-32P672 reports underrun events on a per-channel basis to the host by setting bit STATUS[2] when a TDR is returned to the TDR Free Queue. If a packet underflows near the end of the packet and the next packet on the same channel underflows near the start of the packet, it is possible that only one TDR is returned to the TDR Free Queue with STATUS[2] set even though 2 underrun events occurred.
