For all bits in this register:



‘0’ - The specified sensor input is not considered a part of the pattern.



‘1’ - The specified sensor input is considered a part of the pattern, or the absolute number of sensor

inputs that must have a delta count greater than the MTP threshold or have the Noise Flag Status

bit set is increased by 1.

Bit 7 - CS8_PTRN - Determines whether CS8 is considered as part of the Multiple Touch Pattern.

Bit 6 - CS7_PTRN - Determines whether CS7 is considered as part of the Multiple Touch Pattern.

Bit 5 - CS6_PTRN - Determines whether CS6 is considered as part of the Multiple Touch Pattern.

Bit 4 - CS5_PTRN - Determines whether CS5 is considered as part of the Multiple Touch Pattern.

Bit 3 - CS4_PTRN - Determines whether CS4 is considered as part of the Multiple Touch Pattern.

Bit 2 - CS3_PTRN - Determines whether CS3 is considered as part of the Multiple Touch Pattern.

Bit 1 - CS2_PTRN - Determines whether CS2 is considered as part of the Multiple Touch Pattern.

Bit 0 - CS1_PTRN - Determines whether CS1 is considered as part of the Multiple Touch Pattern.

Base Count Out of Limit Register

The Base Count Out of Limit Register indicates which sensor inputs have base counts out of limit (see

Section 4.4, "Sensor Input Calibration"). When these bits are set, the BC_OUT bit is set (see Section

5.2, "Status Registers").

For all bits in this register:



‘0’ - The base count for the specified sensor input is in the operating range.



‘1’ - The base count of the specified sensor input is not in the operating range.

Bit 7 - BC_OUT_8 - Indicates whether CS8 has a base count out of limit.

Bit 6 - BC_OUT_7 - Indicates whether CS7 has a base count out of limit.

Bit 5 - BC_OUT_6 - Indicates whether CS6 has a base count out of limit.

Bit 4 - BC_OUT_5 - Indicates whether CS6 has a base count out of limit.

Bit 3 - BC_OUT_4 - Indicates whether CS6 has a base count out of limit.

Bit 2 - BC_OUT_3 - Indicates whether CS3 has a base count out of limit.

Bit 1 - BC_OUT_2 - Indicates whether CS2 has a base count out of limit.

Bit 0 - BC_OUT_1 - Indicates whether CS1 has a base count out of limit.
