C Bus 5
RTM Payload Reset RTM Bay MMC Reset (ENABLE*)
RTM_PCIE_PRES Asserted for RTM with PCI Express capability when the AMC is ready to be activated.
RTM_PCIE_BUTTON Asserted for RTM with PCI Express capability to notify OS that the PCI Express links can now be
enabled (for training during activation) or disabled (during deactivation).
RTM Management Power (+3.3V) RTM_+3_3 Power Enable: controls RTM 3.3V management power
RTM PCIE CLK Enable RTM_CLKEN: enables or disables 100Mhz differential clock for PCI Express on RTM
