44 / 71 page  8 Channel Capacitive Touch Sensor with 2 LED Drivers Datasheet Revision 1.1 (08-05-09) 44 SMSC CAP1028 DATASHEET are required than would normally be allowed during the cycle time, the cycle time will be extended as necessary to accommodate the number of samples to be measured. 5.11 Calibration Activate Registers The Calibration Activate register force the respective sensors to be re-calibrated. When a bit is set, the corresponding Capacitive Touch Sensor will be re-calibrated and the bit will be automatically cleared once the re-calibration routine has finished. During the re-calibration routine, the sensors will not detect a press for up to 600ms and the Sensor Base Count register values will be invalid. During this time, any press on the corresponding sensors will invalidate the re-calibration. Bit 7 - CS8_CAL - When set, the CS8 input is re-calibrated. This bit is automatically cleared once the sensor has been re-calibrated successfully. Bit 6 - CS7_CAL - When set, the CS7 input is re-calibrated. This bit is automatically cleared once the sensor has been re-calibrated successfully. Bit 5 - CS6_CAL - When set, the CS6 input is re-calibrated. This bit is automatically cleared once the sensor has been re-calibrated successfully. Bit 4 - CS5_CAL - When set, the CS5 input is re-calibrated. This bit is automatically cleared once the sensor has been re-calibrated successfully. Bit 3 - CS4_CAL - When set, the CS4 input is re-calibrated. This bit is automatically cleared once the sensor has been re-calibrated successfully. Bit 2 - CS3_CAL - When set, the CS3 input is re-calibrated. This bit is automatically cleared once the sensor has been re-calibrated successfully. Bit 1 - CS2_CAL - When set, the CS2 input is re-calibrated. This bit is automatically cleared once the sensor has been re-calibrated successfully. Bit 0 - CS1_CAL - When set, the CS1 input is re-calibrated. This bit is automatically cleared once the sensor has been re-calibrated successfully. 5.12 Interrupt Enable Register The Interrupt Enable registers determine whether a sensor touch or release causes the interrupt pin to be asserted. Bit 7 - CS8_INT_EN - Enables the interrupt pin to be asserted if a touch is detected on CS8 (associated with the CS8 status bit).
