DATASHEET
Bit 6 - CS7_INT_EN - Enables the interrupt pin to be asserted if a touch is detected on CS7
(associated with the CS7 status bit).
Bit 5 - CS6_INT_EN - Enables the interrupt pin to be asserted if a touch is detected on CS6
(associated with the CS6 status bit).
Bit 4 - CS5_INT_EN - Enables the interrupt pin to be asserted if a touch is detected on CS5
(associated with the CS5 status bit).
Bit 3 - CS4_INT_EN - Enables the interrupt pin to be asserted if a touch is detected on CS4
(associated with the CS4 status bit).
Bit 2 - CS3_INT_EN - Enables the interrupt pin to be asserted if a touch is detected on CS3
(associated with the CS3 status bit).
Bit 1 - CS2_INT_EN - Enables the interrupt pin to be asserted if a touch is detected on CS2
(associated with the CS2 status bit).
Bit 0 - CS1_INT_EN - Enables the interrupt pin to be asserted if a touch is detected on CS1
(associated with the CS1 status bit).

Repeat Rate Enable Register
The Repeat Rate Enable register determines the interrupt behavior of the buttons as described in
Bit 7 - CS8_RPT_EN - Enables the repeat rate for Capacitive Touch Sensor 8.
‘0’ - The repeat rate for CS8 is disabled. It will only generate an interrupt when a touch is detected
and when a release is detected no matter how long the touch is held for.
‘1’ (default) - The repeat rate for CS8 is enabled. In the case of a “touch” event, it will generate an
interrupt when a touch is detected and a release is detected. In the case of a “press and hold”
event, it will generate an interrupt when a touch is detected and at the repeat rate so long as the
touch is held. It will not generate an interrupt when a release is detected.
Bit 6 - CS7_RPT_EN - Enables the repeat rate for Capacitive Touch Sensor 7.
Bit 5 - CS6_RPT_EN - Enables the repeat rate for Capacitive Touch Sensor 6.
Bit 4 - CS5_RPT_EN - Enables the repeat rate for Capacitive Touch Sensor 5.
Bit 3 - CS4_RPT_EN - Enables the repeat rate for Capacitive Touch Sensor 4.
Bit 2 - CS3_RPT_EN - Enables the repeat rate for Capacitive Touch Sensor 3.
Bit 1 - CS2_RPT_EN - Enables the repeat rate for Capacitive Touch Sensor 2.
Bit 0 - CS1_RPT_EN - Enables the repeat rate for Capacitive Touch Sensor 1.
