Document Table of Contents The PCIe* Link Inspector LTSSM Monitor

The LTSSM monitor stores up to 1024 LTSSM states and additional status information in a FIFO. When the FIFO is full, it stops storing. Reading the LTSSM offset at address 0x02 empties the FIFO. The ltssm_state_monitor.tcl script implements the LTSSM monitor commands.
