PSD REGISTER DESCRIPTION AND ADDRESS OFFSET
Table
6
shows the offset addresses to the PSD
registers relative to the CSIOP base address. The
CSIOP space is the 256 bytes of address that is al-
located by the user to the internal PSD registers.
Table
7
provides brief descriptions of the registers
in CSIOP space. The following section gives a
more detailed description.
Table 6. I/O Port Latched Address Output Assignments (Note1)
Note: 1. See the section entitled
I/O PORTS, page 51
, on how to enable the Latched Address Output function.
2. N/A = Not Applicable
Table 7. Register Address Offset
Note: 1. Other registers that are not part of the I/O ports.
