Test Clock Input
Eight Sensor Inputs or DIOs configured by the host MCU:
• DIOs also can be configured as extended GPIOs, Direct Touch outputs or External Interrupt Inputs.
• PA1~PA3 are capable of LED dimming control.
Reference input
Four DIOs configured by the host MCU:
• as Extended GPIOs, Direct Touch Outputs or External Interrupt inputs.
• GPIO0~GPIO3 are capable of LED dimming control.
Bidirectional I
I
Touch Interrupt generated only when touch status is changed.
General Interrupts including touch interrupt (TINT) and external interrupts. They can be masked by the host MCU.
