49.5.9.3.3 LPC Reset
The LPC controller does not adhere to the section of the LPC specification that says
“LRESET# is always asserted after LPCPD#”. LRESET # is not always asserted after
LPCPD#.

General Purpose I/O (GPIO)
GPIO are general-purpose I/O signals. These signals can be used for slow-speed,
software-controlled I/O.
This section describes the electrical characteristics of the GPIO interface.
49.5.10.1 GPIO Signal List
For GPIO pin description refer to Table 48-11, “General-Purpose IO Signals” on
page 1744.
