Additional Local I/O Functions
The PP 110/01x supports a variety of I/O functions whose addresses are summarized in Table
9-1.
NOTE
A second LPC Super I/O controller (designated TM Super I/O in Table 9-1) is
located on the AD PP5/001 Transition Module. This device provides some of the
legacy peripheral functions. The parallel port and floppy disk controller sections of
the on-board Super I/O controller (designated Local Super I/O in Table 9-1) are
not used.
