2 / 21 page MK712 TOUCH SCREEN CONTROLLER TOUCH SCREEN CONTROL IDT™ TOUCH SCREEN CONTROLLER 2 MK712 REV N 051310 Pin Descriptions Interrupts Interrupts are controlled by register 6 (see Register Description). The INT pin (pin 2) goes high to signal an interrupt. Interrupts are then cleared by reading any register. However, if the MK712 is in the process of generating an interrupt during a read cycle, then the interrupt is not cleared and INT will stay high. This internal process may take 100ns, and so to guarantee that the interrupt is cleared, two successive read cycles may be necessary. Pin Number Pin Name Pin Type Pin Description 1 NC — No connect. Do not connect this pin to anything. 2 INT Output Interrupt. Goes high to signal an interrupt. Cleared on next read. 3 TOUCH Output Touch signal. Goes low when screen is touched. Goes high when not touched. 4 VDD Power Power Supply. Connect to +5 V or +3.3 V. (Connect all VDDs to same voltage) 5 VDD Power Power Supply. Connect to +3.3 V. 6 XH Touch Screen Pin Connect to X-high on touch screen. (Right side) 7 XL Touch Screen Pin Connect to X-low on touch screen. (Left side) 8 YH Touch Screen Pin Connect to Y-high on touch screen. (Top) 9 YL Touch Screen Pin Connect to Y-low on touch screen. (Bottom) 10 GND Power Connect to ground. 11 GND Power Connect to ground. 12 WR Input Write enable. Active low. 13 RD Input Read enable. Active low. 14 CS Input Chip select. Active low. 15 A2 Input Register address 2. 16 A1 Input Register address 1. 17 A0 Input Register address 0. 18 CLKIN Input Clock input. Typically 14.3 MHz. Best if driven by an IDT clock synthesizer. 19 D7 I/O Data bit 7. 20 D6 I/O Data bit 6. 21 GND Power Connect to ground. 22 VDD Power Power Supply. Connect to +5 V or +3.3 V. (Connect all VDDs to same voltage) 23 D5 I/O Data bit 5. 24 D4 I/O Data bit 4. 25 D3 I/O Data bit 3. 26 D2 I/O Data bit 2. 27 D1 I/O Data bit 1. 28 D0 I/O Data bit 0. |
