CCS/TMS320F28377S: Doubt regarding DCSM's Linkpointer's address

The figure says that the address is 0x78000 but the bolded part of the snippet below assigns the value stored in the location 0x5F000 in a variable called linkpointer why is that being done

unsigned long LinkPointer;
unsigned long *Zone1SelBlockPtr;
int Bitpos = 28;
int ZeroFound = 0;
// Read Z1-Linkpointer register of DCSM module.
LinkPointer = *(unsigned long *)0x5F000;
// Bits 31 30 and 29 as most-sigificant 0 are reserved LinkPointer options
LinkPointer = LinkPointer << 2;
while ((ZeroFound == 0) && (bitpos > -1))
{
if ((LinkPointer & 0x80000000) == 0)
{
ZeroFound = 1;
Zone1SelBlockPtr = (unsigned long *)(0x78000 + ((bitpos + 3)*16));
} else
{
bitpos--;
LinkPointer = LinkPointer << 1;
}
}
if (ZeroFound == 0)
{ Zone1SelBlockPtr = (unsigned long *)0x78020;
}
