Figure 3-15. USB 3.0 SuperSpeed Data Transfer
Note: CY4603 and CY4613 have three port status indicator LEDs for each downstream port;
Table 3-6 describes their functions.
The port status indicator LEDs (DSX_SS, DSX_GRN, DSX_AMB) are grouped according to down-
stream port;
Figure 3-16 and Figure 3-17 illustrate this for the CY4603 and CY4613 boards, respec-
tively.
