RDATA[0] = 1 -> MIPS32 IS BIG-ENDIAN
RDATA[2:1] = 10 -> FULL MERGE MODE
RDATA[3] = 0 -> FIXED (DEBUG)
RDATA[5:4] = 01 -> VRCLK = 166 MHz
RDATA[6] = 0 -> EDINT DISABLED
RDATA[9:7] = 011 -> MEMORY MCLK = 133 MHz
RDATA[10] = 1 -> ROM IS BIG ENDIAN
RDATA[11] = 0 -> NAND FLASH IS 256Mb OR LESS
RDATA[12] = 1 -> USE INTERNAL BOOT ROM
RDATA[15:13] = 000 -> USE NAND FLASH
ATX (SPDIF) = 1 -> USE FCS1B FOR NAND BOOT
