Preliminary Information
14
Table 7 shows the offset addresses to the PSD9XX registers relative to the CSIOP base
address. The CSIOP space is the 256 bytes of address that is allocated by the user to the
internal PSD9XX registers. Table 7 provides brief descriptions of the registers in CSIOP
space. For a more detailed description, refer to section 9.
