PSD MODULE REGISTER DESCRIPTION AND ADDRESS OFFSET
Table 59 shows the offset addresses to the PSD
Module registers relative to the CSIOP base ad-
dress. The CSIOP space is the 256 bytes of ad-
dress that is allocated by the user to the internal
PSD Module registers. Table 59 provides brief de-
scriptions of the registers in CSIOP space. The fol-
lowing section gives a more detailed description.
