protrulerdwr Fields
Bit | Name | Description | Access | Reset |
---|---|---|---|---|
6 | readrule | Write to this bit to have the memory_prot_data register loaded with the value from the internal protection table at offset. Table value will be loaded before a rdy is returned so read data from the register will be correct for any follow-on reads to the memory_prot_data register. |
RW | 0x0 |
5 | writerule | Write to this bit to have the memory_prot_data register to the table at the offset specified by port_offset. Bit automatically clears after a single cycle and the write operation is complete. |
RW | 0x0 |
4:0 | ruleoffset | This field defines which of the 20 rules in the protection table you want to read or write. |
RW | 0x0 |
