Is the GPMC_ERR_ADDRESS register reset by the GPMC_ERR_TYPE.ERRORVALID bit?

The GPMC_ERR_ADDRESS register is able to Write.
What meaning does it have to write?
Does it clear those bits to write?

What happens by writing the GPMC_ERR_ADDRESS bit?

Are the GPMC_ERR_ADDRESS.ILLEGALADD bits reset by the GPMC_ERR_TYPE.ERRORVALID bit?

The GPMC_ERR_ADDRESS.ILLEGALADD bits can be written.
After these bits were written, what occurs?

Hi,

Is it a typo in the TRM that the GPMC_ERR_ADDRESS.ILLEGALADD bits are R/W (Read/Write)?

Is it correct that the GPMC_ERR_ADDRESS.ILLEGALADD bits are R (Read only)?

Hi,

Once I wrote "0x7FFFFFFF" to the GPMC_ERR_ADDRESS.ILLEGALADD field, the GPMC_ERR_ADDRESS register was changed from "0x00000000" to "0x400000AC" and the GPMC_ERR_TYPE register was changed from "0x00000000" to "0x00000211".

Therefore I guess the GPMC_ERR_ADDRESS.ILLEGALADD bits are R (Read only).

Is my guess correct?

Best regards,

Daisuke
