Freescale Semiconductor Technical Data MPR081 Rev 0, 06/2007 Touch Pad Controller The MPR081 is a user interface controller which manages a 16-position rotary touch pad. The MPR081 uses an I2C interface to communicate with the host, which configures the operation, and an interrupt to advise the host of status changes. The interrupt output, IRQ, indicates that rotary status has changed since the www.datasheet4u.com MPR081 was last read. The maximum interrupt frequency can be limited to sacrific.
