45 / 102 page  Multiple Channel Capacitive Touch Sensor and LED Driver Datasheet SMSC CAP1114 45 Revision 1.1 (02-04-11) DATASHEET 6.5 Vendor ID Register The Vendor ID Register stores an 8-bit value that represents SMSC. 6.6 Volumetric Step Register The Volumetric Step Register controls the size of a step to the volumetric data when a slide is detected in the UP and DOWN directions. Bits 3 - 0 - VOL_STEP[3:0] - Determines the volumetric data step when a slide is detected. Each LSB corresponds to a value of ±1. 6.7 Noise Status Registers The Noise Status Registers store status bits that are generated from the analog block if the detected noise is above the operating region of the analog detector. These bits indicate that the most recently received data from the sensor is invalid and should not be used for touch detection. Furthermore, so long as the bit is set for a particular channel, no decisions are made with the data. The queues are not updated, a touch is not detected, and a release is not detected. These bits will also be set if RF noise is detected on any individual sensor. With the exception of CS1, these conditions are OR’d together when setting the bits. For CS1, the S1_RF_NOISE bit will be set when RF noise is detected, and the S1_NOISE bit will be set if the detected noise is above the operating region of the detector. These bits are not sticky and will be cleared automatically if the analog block does not report a noise error.
