20.2
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.
