1.7 Multi-Master Operation Memory Map
When the MCU acts as a slave in a multi-master system, the external bus interface (EBI) translates the
24-bit external address to a 32-bit internal address.
Table 1-3 lists the translation parameters.
0xFFFC_0000–0xFFFC_3FFF 16 KB 1152 Controller area network (FlexCAN A)
0xFFFC_4000–0xFFFC_7FFF 16 KB 1152 Controller area network (FlexCAN B)
0xFFFC_8000–0xFFFC_BFFF 16 KB 1152 Controller area network (FlexCAN C)
0xFFFC_C000–0xFFFC_FFFF 16 KB 1152 Controller area network (FlexCAN D)
0xFFFD_0000–0xFFFF_BFFF 176 KB N/A Reserved

If the allocated size is more than the used size, the base address for the module is the lowest address of the listed address range,
unless noted otherwise.
2
A common configuration is: EBI memory ranges from 0x2000_0000 to 0x2FFF_FFFF; and Calibration memory ranges from
0x3000_0000 to 0x3FFF_FFFF. Hardware does not force any restrictions on allocating memory to the EBI versus calibration bus.
3
The FEC pins are muxed with DATA[16:31].
4
The BAM address range is configured so that the 4 KB BAM occupies 0xFFFF_F000–0xFFFF_FFFF.
