The Sleep Channel control register determine which sensors are sampled when the device is placed
into sleep mode.
APPLICATION NOTE: If this register is updated while the device is in Sleep Mode, then the conversion cycle may
be extended or for the first measurement of the new Capacitive Touch Sensors. It will correct
itself on subsequent measurement cycles.
APPLICATION NOTE: If this register is updated while the device is in Sleep Mode, it is recommended that force a
recalibration routine on newly activated channels.
Bit 7 - GR_SLEEP - Enables the Grouped sensors to be sampled when the device is placed into sleep
mode.
‘0’ (default) - The Grouped Sensors are not sampled when the device is in Sleep mode
‘1’ - The Grouped Sensors are sampled when the device is in Sleep mode. If a tap, slide, or touch
and hold is detected then the appropriate status bit is set and an interrupt generated.
Bit 6 - S7_SLEEP - Enables the CS7 sensor to be sampled when the device is placed into sleep mode.
‘0’ (default) - The CS7 input is not sampled when the device is in Sleep mode
‘1’ - The CS7 input is sampled when the device is in Sleep mode. If a touch is detected then the
status bit is set and an interrupt generated.
Bit 5 - S6_SLEEP - Enables the CS6 sensor to be sampled when the device is placed into sleep mode.
Bit 4 - S5_SLEEP - Enables the CS5 sensor to be sampled when the device is placed into sleep mode.
Bit 3 - S4_SLEEP - Enables the CS4 sensor to be sampled when the device is placed into sleep mode.
Bit 2 - S3_SLEEP - Enables the CS3 sensor to be sampled when the device is placed into sleep mode.
Bit 1 - S2_SLEEP - Enables the CS2 sensor to be sampled when the device is placed into sleep mode.
Bit 0 - S1_SLEEP - Enables the CS1 sensor to be sampled when the device is placed into sleep mode.

The Multiple Touch Configuration register controls the settings for the multiple touch detection circuitry.
These settings determine the sensitivity of this detection and the CAP1014 device behavior.
Bit 7 - MULT_BLK_EN - Enables the multiple button blocking circuitry.
