RM510Q-GL_Hardware_Design 42 / 88
4.3. PCIe Interface
The module provides one integrated PCIe (Peripheral Component Interconnect Express) interface.
⚫ PCI Express Base Specification Revision 3.0 compliant
⚫ Data rate up to 8 Gbps per lane
4.3.1. PCIe Operating Mode
The module supports endpoint (EP) mode and root complex (RC) mode. In EP mode, the module is
configured as a PCIe EP device. In RC mode, the module is configured as a PCIe root complex.
AT+QCFG="pcie/mode" is used to set PCIe RC/EP mode.
Parameter
