Refresh timer. Indicates the multiple of 16 CCLKs between SDRAM refresh cycles. 0x0 = Refresh disabled (POR reset value). 0x1 - 0x7FF = n x16 = 16n CCLKs between SDRAM refresh cycles. For example: 0x1 = 1 x 16 = 16 CCLKs between SDRAM refresh cycles. 0x8 = 8 x 16 = 128 CCLKs between SDRAM refresh cycles
