    252252The generic MMU contains a set of 32 bits registers (or pseudo-registers) that can be accessed by operating system,
    253253through a dedicated MMU driver.
    254 The register index is contained in the 5 LSB bits of the address field (dreq.addr). The value to be written in the register is contained in the data field (dreq.wdata).
     254The register index is contained in the 7 LSB bits of the address field (dreq.addr>>2). The value to be written in the register is contained in the data field (dreq.wdata).

    256256In the case of the MIPS processor, these registers are implemented in coprocessor 2, and are accessed
