PP 41x/03x 9-1
9 ADDITIONAL LOCAL I/O FUNCTIONS
The PP 41x/03x supports a variety of I/O functions whose addresses are summarized in Table 9-1.
NOTE: An LPC Super I/O controller (designated TM Super I/O in Table 9-1) is located on
the AD PP5/001-4xU Transition Module. This device provides some of the legacy
peripheral functions.
