Table 4-42 shows configuration pins assignment to functions when boot mode is the PCIe mode.
BOOTMODE Pins | Field | Value | Description | MCU Only=1 Value |
---|---|---|---|---|
5 | SSC | 0 | SSC Enabled | N/A |
1 | SSC Disabled | |||
4 | Clocking | 0 | PHY clock from external pins | N/A |
1 | PHY clock from internal source |
Table 4-43 summarizes the PCIe pin configuration done by ROM code for PCIe boot device on port 1.
Device Pin | Module Signal | Pull Enable | Pull Direction | Driver Index | Rx En/Dis | Tx En/Dis | Pinmux Sel |
---|---|---|---|---|---|---|---|
TIMER_IO0 | PCIE1_CLKREQn | Enable | Up | 0 | Enable | Enable | 6 |
Note that PCIe SerDes pins do not have pin mux options.
