3.2 Warnings and Notes for All controlCARDs

The controlCARD was modified to use a 25 MHz clock input by default. This change was needed to meet compliance requirements for the EtherCAT Slave Controller(ESC). The ESC, located inside of the F28388D device, is required to share the same clock source as the EtherCAT physical layer (PHYs). This change allows both to share the 25 MHz clock input. For customers not using the ESC, this change is not a requirement.

Early versions of the controlCARDs (MCU063E1, MCU063E2, MCU063A) use a 20 MHz clock. This is compatible with C2000Ware versions V3.01.00.00 and earlier. When using with C2000Ware versions V3.02.00.00 and later, modifications to the PLL settings are necessary. Additionally, controlCARD versions MCU063B and later use a 25 MHz input clock and are only compatible with C2000Ware versions V3.02.00.00 or later.
