≤ 66 MHz.

Multiplied all PLL frequencies in table by 2.

Changed DTMRx to DTIMx.

Changed bit numbers from 63–32 to 31–0.

Changed bit numbers from 63–32 to 31–0.

Added “Unlike the MCF5272, the MCF5282 does not have an independent 
SDRAM clock signal. For the MCF5282, the timing of the SDRAM 
controller is controlled by the CLKOUT signal.”

maximum SDRAM address size is 128 Mbits.”

Changed reset value to 0010_0000_0000_0000.

Changed “PSTCLK” references to “CLKOUT.”

Changed “TEA” to “TA.”

Changed “RAS0” and “RAS1” to “SDRAM_CS0” and “SDRAM_CS1.”
