42 / 48 page ![]() CAP1106 DS00001624B-page 42 2015 Microchip Technology Inc. APPENDIX A: DEVICE DELTA A.1 Delta from CAP1006 to CAP1106 1. Updated circuitry to improve power supply rejection. 2. Added Multiple Touch Pattern detection circuitry. See Section 6.15, "Multiple Touch Pattern Configuration Regis- ter". 3. Added General Status register to flag Multiple touches, Multiple Touch Pattern issues and general touch detec- tions. See Section 6.2, "Status Registers". 4. Added bits 6 and 5 to the Recalibration Configuration register (2Fh - see Section 6.17, "Recalibration Configura- tion Register"). These bits control whether the accumulation of intermediate data and the consecutive negative delta counts counter are cleared when the noise status bit is set. 5. Added Configuration 2 register for noise detection controls and control to interrupt on press but not on release. Added control to change alert pin polarity. See Section 6.6, "Configuration Registers". 6. Updated Deep Sleep behavior so that device does not clear DSLEEP bit on received communications but will wake to communicate. 7. Register delta: Table A.1 Register Delta From CAP1006 to CAP1106 Address Register Delta Delta Default 00h Page 20 Changed - Main Status / Control added bits 7-6 to control gain 00h 02h Page 21 New - General Status new register to store MTP, MULT, and gen- eral TOUCH bits 00h 44h Page 24 New - Configuration 2 new register to control alert polarity, and noise detection, and interrupt on release 00h 24h Page 27 Changed - Averaging Control updated register bits - moved SAMP_AVG[2:0] bits and added SAMP_- TIME bit 1. Default changed 39h 2Bh Page 30 New - Multiple Touch Pattern Configuration new register for Multiple Touch Pattern configuration - enable and threshold set- tings 80h 2Dh Page 31 New - Multiple Touch Pattern Register new register for Multiple Touch Pattern detection circuitry - pattern or number of sensor inputs 3Fh 2Fh Page 32 Changed - Recalibration Configuration updated register - updated CAL_CFG bit decode to add a 128 averages setting and removed highest time setting. Default changed. Added bit 6 NO_CLR_INTD and bit 5 NO_CLR_NEG. 8Ah 38h Page 33 Changed - Sensor Input Noise Threshold updated register bits - removed bits 7 - 3 and consolidated all controls into bits 1 - 0. These bits will set the noise threshold for all channels. Default changed 01h 39h Removed - Noise Threshold Register 2 removed register n/a 41h Page 34 Changed - Standby Con- figuration updated register bits - moved STBY_AVG[2:0] bits and added STBY_- TIME bit 1. Default changed 39h FDh Page 37 Changed - Product ID Changed bit decode for CAP1106 55h |
