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.
