Figure 20.2 shows the GDTA address space (physical addresses). The GDTA consists of a number

of function blocks; the address space is divided into function block units owned by the respective

blocks. However, not all actually existing addresses are on the space; addresses following those in

a function block are mapped as mirror spaces for the function block. For the details of addresses

actually existing in each function block, refer to section 20.3, Register Descriptions. Mirror spaces

also exist in buffer RAM.

Note: The space from H'FE40_3000 to H'FE40_3FFF, excluding the space for registers

P4 area address

DRCL_CTL, DWCL_CTL, DRMC_CTL, DWMC_CTL, DCP_CTL, and DID_CTL is a

reserved area, and write access is prohibited. If write access is made, correct operation

cannot be guaranteed.
