Overview: Components and Features Note: GbE ports (0 and 1) are routed through the PHYs directly to connector P14. Therefore, magnetics are required on the Rear Transition Module (RTM) or baseboard. CPLD: The PmPPC7448 uses a Complex Programmable Logic Device (CPLD) to implement various memory-mapped registers and to control access to the Flash, ROM socket, and enumera- tion of Monarch/non-Monarch systems. RTC: The real-time clock is an ST®Microelectronics M41T00 Serial Access Timekeeper®. Dev
