27 / 240 page ![]() 1.0 Signal/Pin Connection and Description (Continued) 27 www.national.com 1.4.9 Keyboard and Mouse Controller (KBC) 1.4.10 Musical Instrument Digital Interface (MIDI) Port Signal Pin/s I/O Buffer Type Power Well Description GA20 9 I/O INT/OD2 VDD Gate A20. KBC gate A20 (P21) output. KBCLK 111 I/O INTS/OD14 VDD,VSB Keyboard Clock. Transfers the keyboard clock between the SuperI/O chip and the external keyboard using the PS/2 protocol. This pin is driven by the internal, inverted KBC P26 signal, and is connected internally to the T0 signal of the KBC. External pull-up resistor to 5V is required (for PS/2 compliance). The pin is monitored for wake-up event detection. To enable the activity during power off, it must be pulled up to Keyboard and Mouse standby voltage. KBDAT 112 I/O INTS/OD14 VDD,VSB Keyboard Data. Transfers the keyboard data between the SuperI/O chip and the external keyboard using the PS/2 protocol. This pin is driven by the internal, inverted KBC P27 signal, and is connected internally to KBC P10. External pull-up resistor to 5V is required (for PS/2 compliance). The pin is monitored for wake-up event detection. To enable the activity during power off, it must be pulled up to Keyboard and Mouse standby voltage. KBRST 8 I/O INT/OD2 VDD KBD Reset. Keyboard Reset (P20) output. MCLK 113 I/O INTS/OD14 VDD,VSB Mouse Clock. Transfers the mouse clock between the SuperI/O chip and the external keyboard using the PS/2 protocol. This pin is driven by the internal, inverted KBC P23 signal, and is connected internally to KBC T1. External pull-up resistor to 5V is required (for PS/2 compliance). The pin is monitored for wake-up event detection. To enable the activity during power off, it must be pulled up to Keyboard and Mouse standby voltage. MDAT 114 I/O INTS/OD14 VDD,VSB Mouse Data. Transfers the mouse data between the SuperI/O chip and the external keyboard using the PS/2 protocol. This pin is driven by the internal, inverted KBC P22 signal, and is connected internally to KBC P11. External pull-up resistor to 5V is required (for PS/2 compliance). The pin is monitored for wake-up event detection. To enable the activity during power off, it must be pulled up to Keyboard and Mouse standby voltage. P12, P16, P17 6,127, 7 I/O INT/OD2 VDD I/O Port. KBC open-drain signal for general-purpose input and output, controlled by KBC firmware. Signal Pin(s) I/O Buffer Type Power Well Description MDTX 125 O O3/6 VDD MIDI Transmit. MIDI serial data output. MDRX 126 I INTS VDD MIDI Receive. MIDI serial data input. |
