Emerson MVME2500 Real Time Clock Input, Local Bus Controller Clock Divisor, Programming Model

Programming Model

7.7.2Real Time Clock Input

The RTC clock input is driven by a 1 MHz clock generated by the FPGA. This provides a fixed clock reference for the QorIQ P20x0 PIC timers which the software can use as a known time reference.

7.7.3Local Bus Controller Clock Divisor

The local bus controller (LBC) clock output is connected to the FPGA for LBC bus transaction. It is also the source of 1 MHz (CPU_RTC) and FPGA tick timers.
