Value Description
0 Reads return 0. Writes have no effect.
ECC Error Detection Flag. This flag indicates if an ECC error occurred on reading DMA Control
packet RAM.
0 Read: No error occurred.
Write: No effect.
1 Read: Error detected and the address is captured in DMAPAR's ERROR_ADDRESS field.
Write: Clears the bit.
0 Reads return 0. Writes have no effect.
0-FFFh Error address. These bits hold the address of the first ECC error generated in the RAM. This
error address is frozen from being updated until it is read by the CPU. During emulation mode
when SUSPEND is high, this address is frozen even when read.
Note: The error address register will not be reset by PORRST nor by any other reset
source.
