2.2.1.2
SCANLINK and SCANCOL interface
An external CPLD logic is required to take the link signals and collision signals from the GPSI PHYs and shift them
into the switch device. The switch device will drive out a signature to indicate the start of the sequence. After that,
the CPLD should shift in the link and collision status of the PHYS as shown in the figure. The extra link status
indicates the polarity of the link signal. One indicates the polarity of the link signal is active high.
