BERT Registers
Table 11-23 lists the BERT registers. All addresses not listed in the table are reserved and should be initialized with
a value of 0x00 for proper operation. The base address for the port n BERT is 0x104,400+0x80*(n-1) (where
n=1-8 for DS34T108, n=1-4 for DS34T104, n=1-2 for DS34T102, n=1 only for DS34T101). The BERT block was
originally designed for a 16-bit data bus. In this device, each 16-bit register is mapped to the least significant bytes
of the dword.
