DRAM Error Status Register. This register contains status on DRAM errors. The status bits in this register are cleared by writing a 1 to the bit position. The error register is not cleared on reset so software can examine its contents after an error-induced reset. Note - Since this register is not cleared on reset, after a power-on reset the contents of this register are undefined, and the bits could be in an illegal state that could not possibly be generated by any error combination (e.g. MEU bit set with all other bits cleared). Operation while in this illegal state leads to undefined behavior for the register, so software should always clear this register after a power-on reset. TABLE 12-31 shows the format of the DRAM Error Status Register. TABLE 12-31 Register64 DRAM Error Status Register - DRAM_ERROR_STATUS_REG (0x84-0000-0280) (Count 4 Step 4096)
