7. REGISTER DESCRIPTIONS
When the DS325x is configured in either of the two CPU bus modes (HW = 0), the registers shown in Table 7-A
are accessible through the CPU bus interfaces. All registers for the LIU ports are forced to their default values
during an internal power-on reset or when the
RST pin is driven low. Setting an LIU’s RST bit high forces all
registers for that LIU to their default values. All register bits marked “—” must be written 0 and ignored when read.
The TEST registers must be left at their reset value of 00h for normal operation.
On the DS3253, only registers for LIUs 1, 2, and 3 are available. Writes into LIU 4 address space are ignored.
Reads from LIU 4 address space return all zeros. On the DS3252, address line A5 is not present, limiting the
address space to the LIU 1 and LIU 2 registers. On the DS3251, address lines A5 and A4 are not present, limiting
the address space to the LIU 1 registers.

Note 1: Underlined bits are read-only; all other bits are read-write.
Note 2: The registers are named REGn, where n = the LIU number (1, 2, 3, or 4). The register names are hyperlinks to the register descriptions.
Note 3: The bit names are the same for each LIU register set.
