Signal Description
2.25 General Purpose I/O Signals
NOTES:
1. GPIO Configuration registers within the Core Well are reset whenever PWROK is de-
asserted.
2. GPIO Configuration registers within the Suspend Well are reset when RSMRST# is
asserted, CF9h reset (06h or 0Eh) event occurs, or SYS_RST# is asserted.
3. GPIO24 is an exception to the other GPIO Signals in the Suspend Well and is not
reset by CF9h reset (06h or 0Eh).
