8.2.3.15.1 GPP COM1 Serial Routing
The GPP serial interface COM1 is implemented inside the Glue Logic FPGA. The IPMC controls
the serial redirection of the GPP serial interface with the signals COM_ROUTE_A,
COM_ROUTE_B and IPMC_COM2FP. See
Figure 8-10 and Table 8-173 .
Table 8-173 shows all possible routes for the GPP serial interface COM1.
