28 / 257 page  1.0 Signal/Pin Connection and Description (Continued) www.national.com 28 Revision1.2 1.4.9 System Wake-Up Control (SWC) Signal Pin(s) I/O Buffer Type Power Well Description GPIOE10-17, GPIOE40-41, GPIOE42, GPIOE43-47, 1-8 2-21 35 49-53 IINTS VSB Wake-up Inputs. Generate a wake-up event or an interrupt. These pins have programmable debounce protection. RI1 RI2 101 109 IINTS VSB Ring Indicator Wake-up. When low, generates a wake-up event or an interrupt, indicating that a telephone ring signal was received by the modem. KBCLK 125 I/O INTS/OD14 VSB Keyboard Clock Wake-up. Generates a wake-up event or an interrupt, indicating a change in the keyboard clock signal. KBDAT 126 I/O INTS/OD14 VSB Keyboard Data Wake-up. Generates a wake-up event or an interrupt, indicating a change in the keyboard data signal. MCLK 127 I/O INTS/OD14 VSB Mouse Clock Wake-up. Generates a wake-up event or an interrupt, indicating a change in the mouse clock signal. MDAT 128 I/O INTS/OD14 VSB Mouse Data Wake-up. Generates a wake-up event or an interrupt, indicating a change in the mouse data signal. PWBTIN 36 I INTS VSB Power Button In. Active (low) level indicates a user request to turn the power on or off. This pin has debounce protection. PWBTOUT 49 O OD6 VSB Power Button Out. Output for the chip-set Power button input. SLBTIN 35 I INTS VSB Sleep Button In. Active (low) level indicates a user request to enter or exit Sleep mode. This pin has debounce protection. SLPS3, SLPS5 52, 53 I INTS VSB Sleep State 3 to 5. Active (low) level indicates the system is in one of the sleep states S3, S4 or S5. These signals are generated by an external ACPI controller. Pins SLPS3 SLPS5Functionality 1 1 Working state (S0) or sleep states S1 or S2 0 1 Sleep state S3 0 0 Sleep states S4 or S5 1 0 Illegal combination SIOSCI 38 O OD6 VSB System Control Interrupt. Active (low) level indicates that a wake-up event occurred, causing the system to exit its current sleep state. External pull-up resistor to VSB is required. SIOSMI 37 O OD6 VSB System Management Interrupt. Active (low) level indicates that an SMI occurred. External pull-up resistor to VSB is required. ONCTL 39 O OD6 VSB Power Supply On/Off Control. Active level (low) indicates that the power should be turned on. External pull-up resistor is required LED1, LED2 50, 51 O O12/12 VSB LED Drive. These outputs can be connected directly to LED devices. They can be configured as one dual-colored LED or two single-colored LEDs with programmable blink rate for all LEDs. VDDFELL 54 O O3/6 VSB VDD Power Fell. Active pulse (high) indicates that the VDD power supply has been turned off. Optionally, this pin can be used to drive an external circuit that pulses the VSB power to the Keyboard and Mouse, thus resetting them. WDO 55 O O3/6 VSB Watchdog Out. An active pulse (low) of a fixed width; it is generated when a watchdog time-out occurs. |
