45 / 348 page  Revision 1.1 45 www.national.com Signal Definitions (Continued) PWRBTN# AF15 I Power Button. An input used by the power management logic to monitor external system events, most typically a system on/off button or switch. This signal has an internal pull-up of 100 K Ω, a Schmitt- trigger input buffer and debounce protection of at least 16 ms. Asserting POR# has no effect on ACPI. If POR# is asserted and ACPI was active prior to POR#, then ACPI will remain active after POR#. Therefore, BIOS must ensure that ACPI is inactive before GPIO63 is pulsed low. Note: This signal can be pulled down internally by soft- ware control. This is done by enabling internal GPIO63 to be an output, for at least 16 ms (F0BAR0+I/O Offset 20h and 24h). --- PWRCNT1 AE17 O Suspend Power Plane Control 1 and 2. Control signals asserted during power management Suspend states. These signals are open-drain outputs. --- PWRCNT2 AF18 O --- THRM# AE15 I Thermal Event. An active low signal generated by exter- nal hardware indicating that the system temperature is too high. --- 2.4.12 GPIO Interface Signals Name Ball No. Type Description Mux GPIO0 B22 I/O GPIO Port 0. Each signal is configured independently as an input or I/O, with or without static pull-up, and with either open-drain or totem-pole output type. A debouncer and an interrupt can be enabled or masked for each of signals GPIO[0:3] and GPIO[6:15] indepen- dently.
