I don't think it's true, so probably this could look like: | --- | 0x18 EINT_CON (per_bank) | | --- | 0x18 EINT_FLTCON0 (per_bank) | | --- | 0x18 EINT_FLTCON1 (per_bank) | | --- | 0x18 EINT_MASK (per_bank) | | 0x700 EINT_CON (global) | 0x18 EINT_CON | etc.. Also, please use spaces for alignment in the table. Best regards, Krzysztof
