Figure 4-4 SPC blanking time in case of same ID triggered

Figure 4-5 SPC blanking time in case of different IDs are triggered

The nibble low time tlow can be configured to be 3UT or 5UT. This can reduce the overall frame length. The low

time includes the fall time of the edge, therefore it has to be ensured that the fall time of the edge is fast

enough to reach the low level within the configured low time (Figure 4-6).
