12.3.1.5.2 External Bus Control Pin Assignment Register (PAR_BUSCTL)
The PAR_BUSCTL register controls the functions of the external bus control signal pins.
Freescale Semiconductor
1
Address
The selection between the address function and chip select function on each of the A[23:21] pins is determined by the
value of the RCSC field in the CIM reset configuration register.

Note if the port size of the external boot device is 8-bit or 16-bit, and the port size of the external SDRAM is 32-bit,
the PAR_AD register must be written after reset to enable the primary functions on the D[15:0] pins before any
SDRAM accesses are attempted.
