External Bus Interface (EBI)
MPC5566 Microcontroller Reference Manual, Rev. 2
12-6 Freescale Semiconductor
See Section 12.4.2.11, “Non-Chip-Select Burst in 16-bit Data Bus Mode.”
12.1.4.6 Debug Mode
When the MCU is in debug mode, the EBI mode is unaffected and retains control of the EBI.
12.2 External Signal Description
The EBI signal pinouts depend on the type of package. Table 12-3 alphabetically lists the external signals
used by the EBI.
See Chapter 2, “Signal Description,” as not all signals are implemented in all device packages.
