Revision 1.64 (01-15-09)

DATASHEET

APPLICATION NOTE: When the Button Status 1 Register is read, the Group Status register will be automatically

cleared. Therefore, the Group Status register should be read prior to reading the Button

Status Registers

5.2.1

Button Status 1

Bit 7 - UP - Indicates that a slide was detected on increasing sensors (i.e. Sensor 8 -> Sensor 9 ->

Sensor 10). This bit is also set if a press is detected on the “Up” portion of the slider. If the Group

auto-repeat is enabled, then the ALERT# pin will be periodically asserted while a slide or press and

hold event is still detected. This bit is sticky and will remain set until cleared. Once cleared, it will be

re-set when another interrupt is generated in the “UP” direction. This bit is automatically cleared if the

DOWN bit is set.

Bit 6 - DOWN - Indicates that a slide was detected on decreasing sensors (i.e. Sensor 14 -> Sensor

13-> Sensor 12). This bit is also set if a press is detected on the “Down” portion of the slider. If the

Group auto-repeat is enabled, then the ALERT# pin will be periodically asserted while a slide or press

and hold event is still detected. This bit is sticky and will remain set until cleared. Once cleared, it will

be re-set when another interrupt is generated in the “DOWN” direction. t. This bit is automatically

cleared if the UP bit is set.

Bit 5 - CS6 - Indicates that a press was detected on Sensor 6. This sensor can be linked to LED6.

‘0’ - A touch was not detected on the corresponding button.

‘1’ - A touch was detected on the corresponding button.

Bit 4 - CS5 - Indicates that a press was detected on Sensor 5. This sensor can be linked to LED5.

Bit 3 - CS4 - Indicates that a press was detected on Sensor 4. This sensor can be linked to LED4.

Bit 2 - CS3 - Indicates that a press was detected on Sensor 3. This sensor can be linked to LED3

Bit 1 - CS2 - Indicates that a press was detected on Sensor 2. This sensor can be linked to LED2.

Bit 0 - CS1 - Indicates that a press was detected on Sensor 1. This sensor can be linked to LED1.

5.2.2

Button Status 2

Bit 7 - CS14 - Indicates that press was detected on Sensor 14. This sensor is part of the group which
