Memory range lower boundary address bits — The LOW_ADDR[18:11] bits represent bits [18:11] of the
global memory address that is used as the lower boundary for the described memory range.
Memory range lower boundary address bits — The LOW_ADDR[10:3] bits represent bits [10:3] of the global
memory address that is used as the lower boundary for the described memory range.
Write-Protect bit — The WP bit causes the described memory range to be treated as write-protected. If this
bit is set every attempt to write in the described memory range causes an access violation.
