Freescale Semiconductor 2-21
2.3.2.5 External Address / Master Address Expansion / GPIO
ADDR[30:31]_ADDR[6:7]_GPIO[26:27]
ADDR[30:31]_ADDR[6:7]_GPIO[26:27] are the EBI address signals. Use the ADDR[6:7] alternate
signal functions to increase memory for master accesses; these signal cannot be used for slave accesses to
the chip.
