v As utilization of buffer memory
The buffer utilization of switch uses the following definition:
1: Led off
0: Led on
For detail , see the LED timing specification.
v SSRAM Fail
LED[0] : This signal also indicates SRAM chip 0 fail ( continue active low )
during the interval of sequence shift data.
LED[1] : This signal also indicates SRAM chip 1 fail ( continue active low )
during the interval of sequence shift data.
LED Clock : The signal is a discontinue clock for LED signals serial shift
out. The clock period width is 400nS and last 32 cycle with every 52.4ms
repeated.
