 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.
